Polymer physics and chemistry (a) Polymer-polymer interactions in binary amorphous and amorphous-crystalline systems: effects of copolymerization and microstructure (b) Quasi-elastic light scattering from macromolecular solutions (c) Electronic and optical properties of polymers

Present research activities are focused on opto-electronic properties of modified conjugated polymers. A general objective is to maximize quantum yields of photon emission in these systems. One route has been to design macromolecules with alternating chromophoric and non-chromophoric sequences; another has been to use blends of appropriate morphology to enhance excitonic energy transfer. Other areas of interest include membrane modification by ion implantation to increase permselectivity; conformation of solvated chains below the θ-point (coil-globule transitions) and the effect of chain architecture on miscibility in multi-component systems.
