MSE Areas: Polymer chemistry, biomaterials
The Stansbury group activities involve the investigation and development of polymeric networks and photopolymerization directed primarily towards broadly defined biomaterials and bioengineering applications. This includes the design and synthesis of new monomers and novel polymers. The characterization of the polymeric materials extends to the dynamic analysis of polymer structure and property evolution in real time during the polymerization process. As an example, the conversion-dependent progression of polymerization stress has been probed in detail with the fundamental understanding gained directed to the rational design of new polymerization approaches.1 One research theme is heterogeneous polymers, in which the heterogeneity is introduced by polymerization-induced phase separation2, pre-polymerized nanogel additives3or interphases associated with fillers in composite materials.4 Another area involves the development of high performance water-compatible monomers and polymeric materials. In addition to laboratory facilities in Boulder, which facilitate a strong collaboration with Chris Bowman, the Stansbury lab extends to the Anschutz Medical Campus.
