Ÿ Successfully fabricated polyimide (PI) membrane with 248 nm excimer laser photolithography and analyzed it using SEM and optical microscopy.

Ÿ Developed fast and organic-solvent free process for fabrication of pH responsive membranes – reduced fabrication time from over 3 hours to 40 seconds.

Ÿ Studied grafting of polyacrylic acid on polyimide membrane using laser induced free radical photo polymerization and characterized using ATR-FTIR, microscope, TGA and SEM.

Ÿ Examined effect of monomer, crosslinker, laser parameters for effective grafting of polyacrylic acid on polyimide membrane to achieve linear drug release profile.

Ÿ Simplified ablation and grafting process by eliminating use of multiple setups.

Ÿ Functionalized carboxylic acid in membrane by immobilization of glucose oxidase enzyme to develop glucose responsive membranes having potential application in drug delivery device for diabetes treatment.

Ÿ Optimized torrefied soybean loading in HDPE composite without affecting mechanical properties and processing parameters.

Ÿ Studied mechanical performance of injection and compression molded samples using Universal Testing Machine (Instron) and DMA.

Ÿ Synthesized and formulated acrylic based pressure sensitive adhesive by free radical polymerization using solution polymerization and characterized using FTIR & bubble viscometer.

Ÿ Designed and formulated experiments to optimize filler (sodium bentonite) content based on T-peel and lap shear strength.

Ÿ Crosslinked acrylic adhesive with epoxy resin (esterification reaction) to improve T-peel and lap shear strength.

Ÿ Optimized proprietary nano silica filler loading in acrylic based pressure sensitive adhesive (PSA) to improve high temperature performance.

Ÿ Studied PSA adhesion properties using peel (180o) strength and shear strength on different substrates at various dwell times and layer thickness.
