Title:
SOLUTION BLOW SPINNING METHOD TO FABRICATE THIN FILM COMPOSITE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2021/244117
Kind Code:
A1
Abstract:
The present invention provides a method for fabricating thin film composite membrane includes: placing a microporous support on a collector; spraying a first solution onto a surface of the microporous support distal to the collector comprising delivering the first solution through an inner nozzle and simultaneously or prior to said delivering the first solution, delivering a first pressurized gas through an outer nozzle; spraying a second solution onto the surface of the microporous support distal to the collector comprising delivering the second solution through the inner nozzle and simultaneously or prior to said delivering the second solution, delivering a second pressurized gas through the outer nozzle so as to initiate an interfacial polymerization with the first solution to form a thin layer; drying the thin layer at approximately 80℃ to 90℃ for approximately 0.5 min to 5 mins to form the thin film composite membrane. Resulting membrane is also provided.
