Our group is working on structure-property relationship of carbon nanotube (CNT), graphene, clay and other nanofiller based polymer composites. The broad aim of our research efforts is to tailor the chemistry and composition of the composite system so as to obtain the desired and multi-functional properties. We attempt to understand the interaction between polymer and nanofiller by various characterization methods and its effects on mechanical, thermal and electrical properties.
Recently we are also engaged in basic understanding of polymer chain relaxation behaviour in nanocomposites and in polymer blend composites by using dielectric spectroscopy and small-angle x-ray scattering techniques.
Besides we try to develop composites for electromagnetic interference (EMI) shielding and strain-sensing applications. Various strategies are being adopted to improve the EMI shielding and electrical properties of polymer composites.
Electrospun nanofiber is another area, where we try to embed antimicrobial and antibacterial agents into biocompatible polymers in order to study the antimicrobial and drug delivery properties of nanofiber patches.
We also work on polyurethane and carbon foams. The latter foam exhibits some interesting properties; such as oil-water separation. These are some of the research areas that interest to us.
