Computational Polymer Physics

These researchers are carrying out a continuing program of computational research in polymer physics that focuses on elucidating molecular origins of the properties of novel polymer solutions and melts, polymer mixtures, and self-assembled structures of block copolymers.

The group studies the self-assembly of systems that contain block copolymers. Much of the group’s work in this area relies on a self-consistent field theory of polymer conformations in inhomogeneous systems. They have begun to focus on self-assembly of amphiphilic block copolymers in water and other strongly selective small molecular solvents. They are trying to study corrections to the self-consistent field approximation that arise from correlations that are not adequately treated by this theory. This work involves a combination of analytic theory and extensive Monte Carlo simulations of simple models of polymer mixtures and diblock copolymer melts.
