Title: Innovations of Ashwani Kumar in Polymer Science
Introduction
Ashwani Kumar is a notable inventor based in Ottawa, Canada, recognized for his contributions to polymer science. With a total of four patents to his name, he has made significant advancements in the field of materials engineering, particularly in the development of semi-interpenetrating polymer networks and filtration membrane technologies.
Latest Patents
One of Ashwani Kumar's latest patents is focused on a highly microporous thermoplastic/bismaleimide semi-interpenetrating polymer network. This invention aims to synthesize semi-IPNs with molecular sieve characteristics using polyetherimide/bismaleimide (PEI/BMI) chromophore composites through a sol-gel technique. The resulting structure exhibits a tunable and compatible chemical structure with fine morphology, suitable for gas separation membranes. These membranes demonstrate a remarkable fifteen times higher gas flux without a significant decrease in gas permselectivity compared to those made from pure PEL. The chemical structures of these novel semi-IPNs were characterized using FTIR, XPS, and SEM, revealing innovative processes such as in situ simultaneous ethoxylation and anionic polymerization of BMI.
Another significant patent involves the design of feed spacers for filtration membrane modules. These spacers are crucial in promoting fluid mixing and maintaining membrane cleanliness in cross-flow filtration systems. Kumar's novel designs feature elongated strands arranged in parallel rows, optimizing the performance of filtration membranes.
