Dr. Smith is a board director, active consultant for organic & materials chemistry, entrepreneurship, and expert opinion.

Our laboratory combines diverse teams of talented chemists and engineers who focus on the design, synthesis, mechanism, structure/reactivity/property relationships, applications, and technology transfer or direct commercialization of monomers, polymeric materials and composites primarily targeted for the information, energy, composites, and sustainability revolutions.  Multidisciplinary collaborative research areas include, but not limited to: (1) fluoropolymers from fluoroalkenes or hexafluoroacetone for optical, energy conversion, communication, and tailored surface applications (Scheme 1); (2) polyarylene networks and high yield carbon structures and composites from processable intermediates (Scheme 2); (3) renewable and bioabsorbable polymers based on aliphatic polyesters (e.g., PLA, PHA, and derivatives) for packaging, coatings, biomedical applications, and hybrid semi-fluorinated polymers; (4) re-ground rubber recycling via functionalization, grafting, and composite formulation and carbonization (Scheme 3); (5) novel acrylonitrile copolymers for carbon fiber precursors and use in wound healing, (6) thermally reversible crosslinkable resins for smart coatings, and (7) direct fluorination of materials.

Scheme 1. General synthetic routes to semi-fluorinated arylene vinylene ether (FAVE), perfluorocyclobutyl (PFCB), and perfluorocycloalkene (PFCA) materials.

Scheme 2. Bis-ortho-diynylarene (BODA) monomers undergo thermal polymerization to branched processable reactive resins that further crosslink and carbonize to give high char yield carbon/carbon (C/C) composites with excellent consolidation.

Scheme 3. Chemical modification of waste tire rubber for upcycling and creation of new material classes from hybrid functional particles.
