Title:
MODIFIED POLYISOPHTHALOYL METAPHENYLENE DIAMINE ULTRAFILTRATION MEMBRANE, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040435
Kind Code:
A1
Abstract:
A modified polyisophthaloyl metaphenylene diamine (PMIA) ultrafiltration membrane and a preparation method therefor. The modified PMIA ultrafiltration membrane is prepared by using PMIA as a membrane material, using an amphiphilic block copolymer as an additive, and using a non-solvent induced phase inversion method. Provided is an application of the modified PMIA ultrafiltration membrane in water purification and industrial wastewater treatment.
