Prof. A. Kumar obtained his M. Tech and Ph.D. degree from IIT, Kanpur in Material Science. He had done masters in Physics
with Electronics as specialization from Meerut University. His research interest involve Materials Science/Condensed Matter Physics:
Polymer Electrolytes and Conducting Polymers. He has been a faculty member of the department of physics since 1999.
Our research is focused on different properties of conducting polymer nanostructures and polymer electrolytes.
The work involves synthesizing and characterizing of conducting polymer-based nanostructures and nanocomposites
for sensing and biomedical applications. Studies on electrical transport properties of graphene and Transition
Metal Dichalcogenides (TMDCs) based conducting polymer nanostructures for high performance supercapacitorelectrode
applications are also in our domain of research. The group is also focusing on developing polymer electrolytes based
on ionic liquids and Metal-Organic Frameworks (MOFs) for applications in rechargeable batteries. To gain an insight
as to how ionic conductivity in polymers can be understood in terms of the dynamic aspects of local structure,
including changes in coordination number and in the distribution of electronic charge is the prime interest.
Modification of conducting polymer nanostructures and polymer electrolytes upon Swift Heavy Ion Irradiation is one
of our research interests.
