Research Areas
Design , development and characterisation of pi-conjugated macromolecules
Pi conjugated macromolecules are interesting candidates for many opto-electronic applications. Our group is interested in the development of different pi-conjugated systems and fine-tuning of their physico-chemical characteristics by appropriate substitutions. Typical programmes examine the opto-electrical features of 1,3,4 oxadiazole and imidazole based macromolecules.

Nanocomposites for biomedical applications
The focus of this part of our work is the development and characterisation of biocompatible, efficient drug delivery systems based on polymer nanocomposites We try to modify the characteristics of polymers by using suitable nano-modifiers. Poly(lactic acid) modification by nanocellulose is a recent contribution from our group. An ultrasonic investigation of the interaction between silicone rubber and nanohydroxy apetite particles is another recent work from this area.

Blend membranes
Chemical modification of biomacromolecules and blending them with appropriate synthetic/ natural macromolecules for specific applications (typically drug release) is another area of our interest . Of late , we reported the modification of natural rubber latex (and its deproteinised version) with dimethyl aminoethyl methacrylate , using a redox initiator system and subsequent blending with poly vinyl alcohol . The properties such as hydrophilicity, film forming ability , resistance to oxidation and adhesion have been found to be favourably modified through the strategies followed.
We also try to investigate the cure, mechanical, thermal , ageing and transport features of blends modified by novel fillers The filler type, loading and distribution within the matrix are being examined to characterise the systems for specific applications.

Blends: physico-chemical modifications
Hierarchical zeolites for organic synthesis
Conventional zeolites have pore sizes which restrict them from the catalysis involving. bigger molecules We modify zeolites through suitable routes and cause pore enlargement which then can facilitate the anchoring of bigger molecules in their channels to execute catalysis faster.
Zeolite modification by macrotemplates
Modulation of macromolecular characteristics by doping with inorganic complexes
Many inorganic complexes offer the opportunities for excellent modulation of optical properties of macromolecules. We synthesise different organic ligands, link them with suitable transition and inner transition metals and then integrate them with macromolecules for optical and electrical applications.
Inorganic Complex Doped Polymer for optical applications
Transport characteristics of membranes
Under this area we try to develop novel membranes and characterise them in terms of kinetic and thermodynamic aspects. The flux and separation efficiency of the membranes are being evaluated.
