Title:
METHOD FOR MODIFYING POLYMER SEPARATION MEMBRANE BY MEANS OF ULTRASONIC IN-SITU POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO/2017/107317
Kind Code:
A1
Abstract:
A method for modifying a polymer membrane by means of ultrasonic in-situ polymerization, and a polymer separation membrane prepared using the method. Nearby polymer macromolecules or micromolecules are cracked to generate free radicals by means of the cavitation effect of ultrasonic waves, thereby initiating monomers to be grafted on the surface of a base membrane and undergo an in-situ polymerization reaction to form a copolymer modified thin layer. The polymerized monomers selected are conventional, easily available, and low in cost. Moreover, the preparation method is simple, the operation process is controllable, and the membrane material obtained by modification has stable and long-lasting hydrophilic performance, and therefore has a good separation effect when applied to water treatment.
