“Biomaterials & charged Polymers – A complicated domain with interesting dynamics and applications.”
Research Overview
Our focus on Poly-Nano-Bio group, is developing cross-linker free biomaterials and understanding the physicochemical aspects of ionic interactions with charged polymers. The chemically modified polymer biomaterials may result in toxicity and issues with biocompatibility and FDA approvals. Hence, we focus on the physical interactions of polymers to develop biomaterials for different applications. We also emphasis on developing certain theories on charged polymers. Our group actively worked with Tata Steel to develop laboratory demonstrations for several products from low-cost tailing coals.
Research Highlights
Physicochemical aspects of polyelectrolytes and polyampholytes
Biomaterials are prepared using chemically crosslinked polymers to increase their dissolution resistance which in turn induce toxicity. Main emphasis is given to the interactions of the charged polymers to get the desired cross-linker free biomaterials without hampering the biocompatibility.
Interaction perspective of biomaterial development
The biomaterials are usually developed using the trial-and error method and without a scientific knowledge of interactions. The main aim is to study the interactions of polymers and other components and design a better biomaterial showing superior results.
Ionic interactions of polymers
The theories of polymer physics are more aligned towards the neutral polymers. We aim to develop certain theories by studying the ionic interaction (salts, acids) with charged polymers and an applications of these in biomaterial development.
Tailing Coal to Value Added Products
Several projects are successfully completed with Tata Steel in last few years to convert waste to wealth i.e., low-cost tailing coal to value added products like C-slurry (as fuel), Activated-C and Battery Grade electrode materials.
