Latest Patents
Suresh Kumar Jewrajka holds a patent for "Anion exchange membrane for electrodialysis applications and process for the preparation thereof." This invention involves the preparation of novel anion exchange membranes derived 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 by methyl iodide, followed by 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 electrodialysis units. The tricomponent anion exchange membrane, which contains 32 wt % PDMA, 17 wt % PnBA, and 51 wt % PAN, demonstrates improved performance, particularly in terms of low power consumption and high current efficiency during water desalination.
