We at the Instability and Soft Patterning Lab, Department of Chemical Engineering, IIT Kharagpur are looking at issues related to nano scale patterning and ordering of polymer systems, by controlling the self organization and evolution of unstable ultra thin films in various settings. The broad areas interest includes Dewetting, Polymer blends, Soft lithography, Evaporation induced patterning, E-field instability, Colloidal assembly, Liquid Crystal thin films, Spin coating, Nano particles in thin films, Opto-electronic device applications, Super Hydrophobic surfaces etc.

We have a state of art laboratory with facilities like AFM, Optical Microscope, Spin and Dip coaters, Ellipsometer, Goniometer and UV Ozone Chamber. We are funded by DST - Nano Mission, DST - Solar Energy Research Initiative as well as Samsung Electronics, Korea under its GRO program. We also have several international colaborations with universities at Akron, Freiburg etc. and also with several other groups at IIT Kharagpur.
