Studies on phase behavior of polymer blends and block copolymers seek to predict the equilibrium states of these materials in bulk and confined geometries and to apply this knowledge in the design of new materials.

We also investigate amphiphilic comb copolymers and their use as surface-segregating additives and coatings for the preparation of anti-fouling filtration membranes for water treatment and molecular fractionations.

Amphiphilic comb copolymers are also useful as cell-interactive biomaterials , when modified with suitable cell-signaling ligands. We additionally study weak polyelectrolyte multilayers (PEMs) that hold potential for controlled release applications.

Block and graft copolymers incorporating ion-conducting components are being explored as electrolytes for lithium polymer batteries . These materials can also serve as the structure-directing agents for nanocomposite battery electrodes.
