Abstract

The main objective of this study was to prepare thin film nanofibrous composite TFNC membranes based on selfsupport nanofibrous mats To this end polyethylene terephthalate nanofibrous supports were produced by electrospinning technique and subsequently heat treatment was performed to increase mechanical stability of the mats Then interfacial polymerization procedure was applied for preparation of TFNC nanofiltration membranes For comparison the thin film composite TFC nanofiltration membrane was prepared by the same conditions based on polyethersulfone ultrafiltration membrane prepared through phase inversion method Chemical structure morphology and mechanical properties were studied by using ATRFTIR SEM and tensile tests respectively Also filtration performance was investigated by water flux rejection water contact angle and MWCO determination Results showed that the TFNC nanofiltration membrane had higher salt rejection and four times higher water flux than the TFC nanofiltraion membrane Na2SO4 rejection and pure water flux were 93 ± 3 34 ± 23 L/m2h and 67 ± 4 8 ± 09 L/m2h for TFNC and TFC respectively At the end the filtration performance of PET TFNCNF membrane was compared with other nanofibrous nanofiltration membranes
