Thin film composite membranes with modified polysulfone supports for organic solvent nanofiltration

► Synthesis of the novel SPESS copolymers based on three different diphenols. ► Modification of PS membrane using copolymers to achieve the chemical stable support. ► Evaluation of SPESS effect on chemical resistant of PS support as conceptual model. ► Synthesis and evaluation of TFC SRNF membranes using chemically modified supports.
