Research

The Moore group is dedicated to the professional development of next-generation scientists and educators who will impact the world with their skills and knowledge. The group’s research integrates ideas from physical organic chemistry and engineering with polymer synthesis to invent mechanically responsive materials. Motivated by the technological need for materials that are safer and last longer, experiments are designed to understand the fundamental science of mechanochemical transduction, which in turn helps in the design of polymers that produce chemical signals or undergo chemical reactions following mechanical activation. Specific examples include materials that heal themselves, warn of high stress, or repair electrical circuits. Recently, the Moore group partnered with frequent collaborators Nancy Sottos and Scott White to demonstrate plastics that not only heal after damage, but regenerate, thanks to reactive fluids pumping through vascular channels within the material, similar to blood in a circulatory system.

Designing New Macromolecular Architectures

Conjugated, carbon-rich macromolecular architectures of nanoscale dimension are a class of organic materials that exhibit unique functional properties depending on the structural framework. Applications include sensory materials for explosives detection, active layers for nanofiltration membranes, and precursors to novel carbon-based anodes in batteries. The Moore group is known for its success in developing, adapting, and utilizing modern synthetic methods to construct complex, yet well-defined, carbon-rich materials. We have demonstrated the synthesis of shape-persistent macrocycles on a multi-gram scale via alkyne metathesis. Utilization of this dynamic covalent chemical reaction enables self-correction during cyclooligomerization. Due to this reversibility, the macrocycle product distribution is under thermodynamic control. However, the ability to predict the products in these reactions is difficult because the design rules for dynamic macrocylization have yet to be established. This gap in knowledge points to the need for a systematic investigation of the parameters that govern cyclooligomerization in alkyne metathesis reactions under thermodynamically controlled conditions. Ultimately, these systematic studies will enable targeted construction of complex macrocycles from rationally designed precursors. Novel architectures are being designed as modulators of fibrillar networks as described below.

Molecular Modulators for Controlled Growth of Fibrillar Networks
Despite the considerable work on self-assembled fibrillar networks (SAFNs), little progress has been made in controlling gel polymerization, structures, and dynamics. Using novel macromolecular architectures we are investigating a general mechanism of fibrillar growth that we call reversible-deactivation fibril assembly (RDFA). This process bears direct analogy to the mechanism of living radical polymerization but is based on the non-covalent assembly of 1D filaments. Our initial goal is to achieve reversible, selective attachment of a molecular modulator to the growing ends of a self‑assembling fibril, thereby controlling the rate of fibril growth.

New Polymeric Materials

Several members of the Moore group are working on projects related to development of novel polymeric materials to meet the challenges of today`s world. We are specifically interested in generation of polymers for applications ranging from compartmentalization and on-demand release of actives, smart packaging of transient electronics to functional membranes for water purification.

Compartmentalization and On-demand ReleaseCompartmentalization is a powerful concept in biology that enables organisms to isolate and carry out multiple functions in an interdependent fashion. The growing needs of isolation and targeted delivery of actives require development of next generation synthetic compartmentalized systems. To meet these needs, our group pursues the synthesis and development of new stimuli-responsive polymeric materials that can rapidly and irreversibly depolymerize on triggering. Such criteria can be met via the development of polymers that are thermodynamically unstable at room temperature, yet kinetically stabilized from depolymerization. We are currently exploring a variety of new depolymerizable polymer architectures, while also exploiting the use of known polymers that possess such qualities in pursuit of applications such as packaging of transient electronics, disappearing materials, shell-walls for triggerable microcapsules, and polymeric materials capable of remodeling or shape-changing phenomena.

Efficient encapsulation of active cargo is another interest of our research. Emulsion templated encapsulation relies on a discrete control of the emulsifier, as well as the continuous and discontinuous phases. Unlike conventional oil-in water emulsions, the encapsulation of hydrophilic actives via water-in-oil emulsions, i.e. inverse emulsion, is far less studied. We pursue the basic understanding of how a metastable emulsion is formed and further locked down via interfacial polymerization with different techniques including microfluidics. From this standing point, we expect applications in encapsulation of curing agents and on-demand release.

Functional Membranes for Water Purification
Finding ways to efficiently purify toxins from water is rapidly becoming a global issue as the world's supply of drinking water steadily decreases. The purpose of this project is to improve the filtration properties of existing water filtration membranes to remove various contaminants (organics, arsenates, etc.) through covalent modification without adversely affecting the physical properties of the film, such as water flux. Two areas of modification are currently being investigated; the covalent attachment of transport modifiers to the polyamide active layer and direct modification of the support. We have found that rejection of an organic surrogate and various salts is enhanced without any long-term loss of efficiency and without significant increase in the water flux of the membrane.

Touch-and-Go Reactions
Here the concepts of catalysis and initiation are applied to a pair of polymer interfaces. Our idea for a "touch-and-go" (TAG) reaction is that two components of a catalyst are grafted to different surfaces; when the surfaces come into contact or "touch," catalyst formation proceeds, causing the reaction to proceed or "go." Thus, a molecular reaction would be controlled by the spatial proximity of macroscopic or microscopic objects. Our goals include proving the feasibility of a TAG reaction and quantifying the parameters that influence rates. Once the feasibility of the TAG reaction has been shown, we will explore various reactions, surface topographies and applications.

Self-Healing Polymers

The development of sacrificial fibers has brought self-healing into common manufacturing materials such as fiber-reinforced composites. With the “VaSC” method (Vaporization of Sacrificial Components), we have created microvascular composites with channel lengths up to one meter. Pluripotent composite materials are manufactured by circulating fluids with unique physical properties where the solid phase provides strength and form and the liquid phase provides interchangeable functionality.

Using the generality and compatibility of vascularized composites, our group is exploring multi-stage healing fluids. The liquid healing agents used in microvascular-based healing systems wick into internal cracks and surface scratches to effectively glue the material together. When a material is catastrophically damaged and loses mass (e.g. ballistic impact), these traditional healing systems fail to replace the lost material and drip out of the damage region. We created a two-stage polymeric approach that incorporates monomer gelation with polymerization to regenerate material approximately 100 times larger than previously possible. Two healing fluids were created that are inert until mixed. Once the solutions mix, they quickly react to form a gel scaffold which holds the material in the damage. Additional fluids are deposited and gel until the entire damage is filled. A subsequent polymerization stage recovers the mechanical properties of the original material. This two-stage approach can heal punctures up to 9 mm in size and has applications ranging from aerospace to civil infrastructure.

Our self-healing research is done in collaboration with the Autonomous Materials Systems division of theBeckman Institute at the University of Illinois.

Mechanochemistry

At the intersection of mechanics and chemistry, mechanochemistry is a subject that embraces many everyday phenomena including wear and abrasion, friction and lubrication, and stress-accelerated degradation of materials. Our concept of a mechanophore is a stress or strain activated molecular unit that can be inserted into a polymeric material to provide a molecular-scale reading of the local mechanical state or to transform materials properties in response to the local mechanical environment. A few key mechanochemical research themes within the group include: Damage Sensing, Catalysis, and shockwave energy dissipation. Our mechanochemistry research is done in collaboration withthe Autonomous Materials Systems group of the Beckman Institute at the University of Illinois.

Shock wave energy dissipation (SWED) by Mechanochemically Active Materials
Dissipating shock wave energy from detonation is necessary to protect soldiers from traumatic brain injury. Shock waves cause a sudden spike in pressure and temperature when passing through a system. We are developing mechanochemically active materials that respond to these high pressures and undergo chemical transformations that dampen the shock wave energy. This project involves: i) designing and synthesizing molecules that can withstand impinging shock waves; ii) identifying and developing chemical transformations that are activated by shock waves, dissipate energy, and are potentially reversible; and iii) identifying the effect of chemical bonds and atoms involved in chemical transformations on capacity of SWED.

Autonomically adaptive materials
Materials systems with reusable building blocks are attractive for autonomically adaptive structures that remodel themselves in response to aging or stress. Nature uses depolymerization and repolymerization cascades to recycle monomeric building blocks in biomaterials. For synthetic materials, remodeling has the potential to extend device lifetime by removal and replacement of damaged regions or by restructuring parts to meet changing demands of their use. The group has initiated work aimed at utilizing mechanically-triggered depolymerization of metastable polymers followed by their repolymerization towards the goal of autonomically adaptive polymeric materials. Mechanically-triggered depolymerization has many other potential applications (e.g. microcapsules) where mechanical force can initiate the breakdown of shell walls to release stored cargo.

Mechanoacids
We are learning to design mechanoacids that are selective to mechanical stress and to ultimately couple mechanical stress to acid catalysis within polymeric materials. Mechanocatalysts have the potential to favorably change the chemistry of a polymer by turnover, and may lead to unprecedented mechanoresponsive materials. Major areas of focus are synthetic design of mechanoacids, coupling mechanoacids to synergistic chemistry in polymers, and effective analytical methods to study these unconventional chemical cascades in polymers.

Sustainable Materials
Waste reduction is key to a sustainable materials landscape, and it is achievable through life extension and recycling of polymer materials. We seek to extend the lifetimes of widely used polymer materials by incorporating mechanically triggered damage sensing and healing functionalities. When damage occurs, the mechanophores locally activate to report damage or initiate healing. Major areas of focus to achieve these goals are learning structure-property relationships for efficient force transduction in polymers, chemical synthesis of functional mechanophores, and streamlined analytical tools to study these mechanochemical reactions.

Ultimately we believe our group is well positioned to realize the next major advancement in the field of mechanochemistry as well as further our understanding of matter as it experiences mechanical energy input.

Energy Storage Materials

The Moore group is actively contributing to the development of materials for the next generation energy storage systems. Our main projects are the preparation and study of new redox active molecules, electrolytes for non-aqueous media, and polymeric membranes and separators.

The Role of Macromolecular Architecture on Redox Active Molecules
As part of our work with the Joint Center for Energy Storage Research (JCESR), new redox active materials as catholytes and anolyte are being developed for flow batteries. Current redox-active molecules (ROMs) have several limitations such as low solubility, membrane crossover, irreversible adsorption on electrode interfaces, high viscosity at high concentrations, and adverse effects on ion and electron transport. Changing the chemical structure of the ROM partially solves these limitations, but fails to address issues such as stability and solubility. A different approach is to incorporate the ROMs into macromolecules such as dendrimers, polymers and colloid particles. A systematic study of molecular architecture and size Is being pursued to learn new ways to mitigate unwanted redox pathways, promote desired redox reactions, and maximize concentration while minimizing viscosity.

Improve the Safety and Longevity of Lithium-ion Batteries
As part of our work with the Center for Electrochemical Energy Storage (CEES), safer battery separators are being developed. An ideal energy storage system should possess high energy density, the ability to release power at a constant rate and a long life span, but foremost, it must be safe to operate. Malfunctions of lithium-ion batteries could have a serious industrial and economic impact. Among the many components of a lithium-ion battery, the battery separator is a crucial module that has direct influence on the battery’s life, safety, and performance. Commercially available battery separators do not have a high thermal stability; they experience shrinking at elevated temperatures causing an internal shortage between electrodes during battery operation. This internal shortage will lead to thermal runaway and safety hazard may occur at any time. Currently under investigation in our group is a high temperature resistant battery separator aiming at improving the safety, abuse tolerance and life span of lithium-ion battery. We are also designing materials to mitigate specific degradation pathways in lithium-ion batteries, to better understand the aging mechanisms and improve battery lifetimes. Investigations are focused into inhibiting reactions that lead to lifetime and capacity fading, such as the breakdown of the solid electrolyte interface (SEI) and fatigue of the electrodes themselves. For instance, spinel type LiMn2O4 cathodes have been shown to release Mn ions, which have a negative effect on the anode material. Materials that can foster repair mechanisms of the SEI as well as alter the terminal reaction of the dissolved Mn ions are being pursued. These studies will aid in the creation of longer-lived batteries for use in existing technologies, and help identify important alterations that should be considered in the next generation of battery materials.
