Surface modification of polyarylene sulfide sulfone membrane by coating with polydopamine

Polyarylene sulfide sulfone membrane was surface-modified by coating with polydopamine to improve its hydrophilic property and permeation performance, and owing to its favorable solvent resistance, it could be applied in the filtration of organic wastewater. The change in the morphology and chemical properties was ascertained by SEM and FTIR, which suggested that polydopamine was adsorbed at the polyarylene sulfide sulfone (PASS) membrane. It was confirmed that the hydrophilic property of PASS membrane was enhanced through water contact angle measurement. Moreover, it possessed an improved flux compared with the pristine PASS membrane even after high temperature and organic solvent treatment.
