Amphiphilic Graft Copolymers for Interfacial Assembly, Encapsulation, and Controlled Release

Kurt Breitenkamp, Bryan Parrish, Rebecca Breitemkamp, and Todd Emrick. University of Massachusetts Amherst, Amherst, MA

Conventional polymer materials, such as polyolefins and aliphatic polyesters, can be tailored with organic and polymeric functionality to broaden greatly their potential range of biomaterials applications. For example, amphiphilicity provide an oil-water interfacial activity to polymer materials, allowing an encapsulation of one phase in a matrix of the other phase. When the polymers used in such assemblies contain reactive functionality, cross-linking chemistries can then convert interfacial assemblies into capsular materials. Tailoring cross-linking chemistry and polymer functionality leads to new systems for controlled release in, for example, targeted drug delivery applications.
