Introduction

Asit K Roy is a notable inventor based in Seguin, TX (US), recognized for his contributions to the field of microporous membrane technology. He holds a total of 3 patents, showcasing his innovative approach to enhancing membrane performance for various applications.

Latest Patents

One of his latest patents is titled "Process for charge modifying a microporous membrane." This invention involves a cationic charge modified microporous membrane that comprises a hydrophilic organic polymeric microporous membrane. The membrane is bonded through a cross-linking agent to a charge modifying amount of a cationic charge modifying agent, which is typically an aliphatic amine or polyamine, with tetraethylene pentamine being the preferred choice. The cross-linking agent used is an aliphatic polyepoxide with a molecular weight of less than about 500, specifically 1,4 butanediol diglycidyl ether. The microporous membrane is preferably made of nylon. The process for applying the charge modifying agent involves contacting the membrane with an aqueous solution of the charge modifying agent, followed by treatment with a substantially aqueous solution of the cross-linking agent. This method utilizes high purity water, ensuring the production of membranes suitable for filtering ultra-pure water, which is essential in the manufacturing of electronic devices. Notably, this membrane exhibits a significantly low 'flush-out' time compared to existing cationic charge modified microporous membranes and unmodified microporous membranes.
