A novel positively charged composite nanofiltration membrane was prepared by coating the casting solution of 2-hydroxypropyltrimethyl ammonium chloride chitosan(HACC) on polysulfone ultrafiltration membrane and cross-linking with epichlorohydrin.

Synthesis and properties of high temperature resistant copoly(aryl ether sulfone)s containing a 4-fluorophenyl group

Three poly(aryl ether sulfone)s containing 1,4-naphthylene moiety were prepared by the nucleophilic polycondensation of 1-chloro-4-(4-chlorobenzenesulfonyl)naphthalene(CCBSN) with 4,4-isopropylidene diphenol(BPA), 1,4-hydroquinone(HQ) and 4-(4-hydroxyphenyl)(2H) phthalazin-1-one(DHPZ), respectively.

In order to increase the hydrophilicity and mechanical strength of gas dehydration membrane simultaneously, poly(ether sulfone) was sulfonated using sulfuric acid, and a series of product(SPES C) with different sulfonation degree were obtained.

lntegrally skinned asymmetric poly(ether sulfone)membranes were made by dry/wet phase inversion processes.
