1.Microphase separation in charged-neutral block copolymers

We use mesocale modeling techniques to develop a macromolecular understanding of

microphase separation in block copolymers of different architectures containing charged

and neutral blocks. Predictions of the models are compared with the experiments.

2. Planar polyelectrolyte brushes: lateral segregation

Rigorous quantitative description of the dielectric function of inhomogeneous polymers (neutral or charged) is lacking and is a long-standing problem. We have developed mesoscopic methods to compute the dielectric function of polymers in inhomogeneous media in a self-consistent manner.

3. Local structure and dynamics of polymer melts

We use molecular dynamics simulations to understand the chain packing and dynamics of polymers in the melts. In particular, the effect of polymer backbone flexibility on the chain packing and the dynamics has been the focus of our research.
