Title:
POLYMERIC NANOFILTRATION MEMBRANE, AND PREPARATION THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/016671
Kind Code:
A1
Abstract:
A polymeric nanofiltration membrane, and the preparation therefor and a use thereof. The polymeric nanofiltration membrane contains hydrophilic nano composite material nitrogen-doped hollow porous carbon spheres. A preparation process for the polymeric nanofiltration membrane is: adding polyether sulfone, polyvinylpyrrolidone, and the nitrogen-doped hollow porous carbon spheres into a solvent, carrying out ultrasonic stirring to obtain a homogenous suspension, then sequentially carrying out baking and ultrasonic treatment to obtain a homogenous and bubble-free suspension, pouring the homogenous and bubble-free suspension on a glass plate for casting in a thin membrane, immediately soaking the thin membrane in distilled water for coagulating bath, separating the thin membrane from the glass plate after the thin membrane is solidified, drying and storing the thin membrane between sheets.
