Fabrication and characterisation of a polyamide thin-film composite membrane on a nylon 6,6 substrate for isopropanol dehydration

Thin-film composite (TFC) is feasible for use in isopropanol (IPA) dehydration by pervaporation (PV) for its superior performance and strength. The hydrophobic substrate membrane allows the penetration of the diamine monomer into the pores, which leads to flux reduction. Furthermore, hydrophobic pol...
