Polymer Solids and Blends
Our current work focuses on the role of randomly incorporated comonomer units (defects) on the morphology and mechanical properties of polymers. Crystalline fraction, melting temperature, and mechanical and optical properties are controlled by the amount and, to a lesser extent, the type of comonomer.
With well-characterized materials we can compare experimental results to theory in a meaningful way. Our research addresses a number of fundamental questions about semicrystalline polymers: What establishes the noncrystalline fraction of semicrystalline polymers? How do semicrystalline polymers melt? How do crystalline fraction and morphogy affect tensile deformation mechanisms?
