Title: Innovations of Sreekumaran Thampy
Introduction
Sreekumaran Thampy is a notable inventor based in Bhavnagar, India. He has made significant contributions to the field of materials science, particularly in the development of anion exchange membranes. With a total of 4 patents to his name, his work has implications for various applications, including electrodialysis.
Latest Patents
Thampy's latest patents include an innovative anion exchange membrane for electrodialysis applications. This invention focuses on the preparation of novel anion exchange membranes from bicomponent or tricomponent copolymers that contain both quaternizable and cross-linkable moieties. The bicomponent copolymers consist of polyacrylonitrile and poly(2-dimethylaminoethyl) methacrylate, while the tricomponent copolymers include polyacrylonitrile, poly(2-dimethylaminoethyl) methacrylate, and poly(n-butyl acrylate). The quaternization of dimethyl amino groups of the copolymer by methyl iodide, followed by the cross-linking of acrylonitrile groups using hydrazine hydrate, results in an anion exchange membrane with desirable properties. These properties include a high ion exchange capacity of 1.30-1.50 meq/g and a high transport number of 0.92-0.93, making it suitable for direct use in an electrodialysis unit. Additionally, the tricomponent anion exchange membrane, which contains 32 wt % PDMA, 17 wt % PnBA, and 51 wt % PAN, exhibits improved performance in terms of low power consumption and high current efficiency during water desalination. Another patent describes a greener process for preparing anion exchange membranes, which eliminates the use of chloromethyl ether, showcasing the membrane's equivalent or superior performance compared to traditional methods.
