Title:
NANOPARTICLE-MODIFIED SWELLING-RESISTANT SULFONATED POLYETHERSULFONE NANOFILTRATION MEMBRANE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/258587
Kind Code:
A1
Abstract:
A swelling-resistant sulfonated polyethersulfone nanofiltration membrane, comprising an ultrafiltration support layer and a nanofiltration separation layer loaded on the ultrafiltration support layer, wherein both the ultrafiltration support layer and the nanofiltration separation layer are formed by phase inversion of sulfonated polyethersulfone, and both the ultrafiltration support layer and the nanofiltration separation layer are subjected to crosslinking treatment by a crosslinking agent; the ultrafiltration support layer casting solution comprises nanoparticles, and the nanofiltration separation layer casting solution does not comprise nanoparticles.
