Abstract
null null The sulfonated polyethylenimine (SPEI) was designed and employed to prepare high-performance loose nanofiltration (NF) membranes. A simple ring-opening reaction of polyethylenimine with 1,3-propanesulfonate (1,3-PS) was firstly conducted to synthesize SPEI. Then NF membranes were obtained by the cross-linked reaction between SPEI and trimesoyl chloride (TMC) via interfacial polymerization. Thanks to the restraining effect on...
