Fabrication of Temperature-Responsive Membrane (PES/GO-g-PNIPAM) for EfficientSeparation and Recovery of Dyes in Wastewater Treatment

Nanofiltration membranes are used in organic dye purification, allowing water recycling and productrecovery. In this work, first, graphene oxide was synthesized using the improved Hammers method, then it wasfunctionalized using vinyltriethoxysilane. In the next step, N-isopropylacrylamide monomer was polymerized onthe surface of graphene oxide using a free radical process. The temperature-responsive membrane wasfabricated during phase inversion process using non-solvent. The performance of the membrane wasinvestigated at two temperatures of ۲۵ and ۶۵℃ and showed good results.
