Title:
COMPOSITE ULTRAFILTRATION MEMBRANE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/199554
Kind Code:
A1
Abstract:
A composite ultrafiltration membrane material and a preparation process thereof. The ultrafiltration membrane material consists of an intercalation-modified α-zirconium phosphate nano-powder and a membrane material body. The chemical general formula of modified material in the intercalation-modified α-zirconium phosphate nano-powder is R4NX. In the chemical general formula R4NX, the four R groups are the same or different, and X in the chemical general formula is one or more among fluorine, chlorine, bromine, iodine, inorganic acid root and carboxylate.
