Functional polymers and networks

We study the formation of polymers and polymer networks with interesting structures and properties. For example, we use precipitation polymerization of crosslinking monomers in select solvents to form clean, mono-disperse microspheres of 2 to 18 micrometer diameter, that are colloidally stabilized by the ongoing deposition of new polymer nanogels. We are learning how to use this sequential, layer-by-layer growth process to inscribe layers of unique structure and composition, using thermal cycling as well as injection of co-monomers, during particle growth. This results in direct formation of multi-layered microspheres with defined onion structures.
