Synthesis of Polyols
The polyols produced by the ring-opening polymerization of epoxides are one of the core raw materials for various polyurethane applications. Most of the current epoxide based polyols are being produced by simple base catalysts like KOH. Thus obtained PPG has been studied as a soft segment material for foams, with less spectacular properties for elastomers. However, in the early 1990s, advances in zinc hexacyanocobaltate-based double metal cyanide catalyst used to produce PPG diols, resulted in a substantial improvement in the levels of polyfunctionality and molecular weight a narrowing of the molecular weight distribution, and a lowering of viscosity. The resulting PPG polyols of narrow MWD and ultra-low monol content allow them to yield polyurethane with superior mechanical properties.

Microfluidics and Fabrications

We are concentrating on fabricating functional materials in nano/micro range using macromolecules through a Microfluidics approach. T-Junction and/or flow-through microchannel fabrication is achieved by a DRIE or PDMS based technique. Polymer microcapsules with controlled functional properties can be developed by this advanced technology. Synthesis and stabilization of nanoparticles is another thrust area of our research. This stabilization process requires a dynamic interdisciplinary effort spanning the fields of chemistry, material science, biology, engineering etc. Using functional block copolymers as stabilizing templates we are able to prepare aggregation free nanoparticles, thereby enhances the quantum confinement effects.

Functional Polymer Synthesis

Our research group provides the leading role in innovative polymer synthesis by controlled radical polymerizations techniques like ATRP, NMFRP, RAFT etc. We are also specialized in the synthesis of polymer-peptide conjugated macromolecules by combining CRP techniques with ring opening polymerization methods. These polymers are demonstrated as ideal building blocks for advanced materials due to their well-defined nature, ease of synthesis, and rich chemistry.

Supramolecular Materials

One of key aims of modern chemistry is to explore and exploit the phenomenal complexity of matter. Inorganic building blocks play a significant role in the self-organized assembly of many biological structures. We are probing the ground rules for biomineralization in the hope of applying them to the self-assembly of practical materials with complex hierarchical structures.
