Research Interests

1. Reversible-Deactivation (‘Living’) Radical Polymerizations

We have significant experience in new radical polymerization methods that have been developed in recent years, including atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT) polymerization and nitroxide-mediated polymerization (NMP). Work in our group is examining what factors affect the mechanism and kinetic parameters, as well as looking into alternate methods of controlling polymerizations. We also utilize these polymerization methods to make novel materials, in particular block copolymers and nanocomposites, for various applications.

2. Novel Methods to Synthesize Degradable Polymers

We have shown that thiol-ene chemistry, a step-growth mechanism of polymerization, can be applied to make materials that are amorphous or semicrystalline, photocurable, undergo surface erosion and have controllable degradation rates, starting from only several hours up to weeks. Thiol-ene chemistry is also quite simple and has readily available monomers, and the degradable functionality resides in the main chain, rather than a side chain, which reduces the molecular weight of the degradation products when compared to chain growth polymerizations. Thus, using thiol-ene chemistry to make polyanhydride network polymers provides significant flexibility in tailoring characteristics such as crosslink density, functionality and hydrophilicity.


3. Novel Polymer Particle Synthesis

We are developing new methods for polymer particle synthesis based on water-borne thiol-ene/yne polymerizations. These polymerizations leverage multiple ‘click’ chemistry attributes so that colloidal particles can be made quickly and efficiently, with stoichiometrically-controlled chemical functionality, uniform crosslinking, and using an environmentally friendly reaction medium (water). This provides a significant opportunity to construct a new and transformational paradigm in polymer colloids, one that will result in sustainable, environmentally friendly, and high impact technologies.

4. Novel Chemical-Mechanical Planarization (CMP) Technologies

CMP is both a necessary and enabling technology in the integrated circuit manufacturing industry.  Essentially it is the polishing of metal and non-metal surfaces with a pad and slurry so that the surface is globally flat and locally perfect.  We focus on developing new chemistries that relate to particle-surface interactions that aim to improve surface quality yet provide fast material removal rates.
