WIPO Patent Application WO/2021/244162
Kind Code:
A1
Abstract:
A non-woven fabric substrate-supported polyethylene nanofiltration membrane, comprising a non-woven fabric substrate (3), a polyethylene microporous membrane (2), and a nanofiltration membrane layer (1). The polyethylene microporous membrane (2) is supported on the non-woven fabric substrate (3), so as to obtain a non-woven fabric-supported polyethylene microporous membrane; and the nanofiltration membrane layer (1) is formed on the non-woven fabric-supported polyethylene microporous membrane by means of the interfacial polymerization of a polyamine aqueous-phase monomer and a polyacid chloride oil-phase monomer.
