Polyethylene sulfone
WebJun 27, 2016 · The chemical depolymerization of common industrial plastics has recently attracted significant interest as an approach to mitigating environmental waste (1–4).To identify new roles for waste materials, new and inexpensive processes must be developed using polymers as starting materials. WebApr 8, 2024 · Fabrication of high-dye/salt-separation-performances and chlorine-resistant nanofiltration (NF) membranes are crucial for dye desalination. In this study, a thin-film composite NF membrane (PES–DPS) was prepared through the interfacial polymerization of 3,3′-diaminodiphenyl sulfone (DPS) and trimesoyl chloride. Because of the low reactivity …
