1. 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. Degradable network polymers
We have shown that thiol-ene chemistry, a step-growth mechanism of polymerization, can be applied to make materials that are elastomeric, photocurable, undergo surface erosion and have controllable degradation rates, starting from only several hours. 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 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. Nanocomposite structures for photovoltaic applications
We are interested in using block polymers to pattern TiO2 nanoparticles onto conducting glass-these materials may find use in dye-sensitized solar cells and other photovoltaic devices.
