Abstract

In this research, a novel type of pervaporation membrane was developed by (polydimethylsiloxane( PDMS)/graphene oxide(GO))/poly valerolactone (PVL) composite membrane. This prepared membrane was used to separate ethylene dichloride from water. The electrospinning method was used to nanofiber PVL preparation as a support layer for the composite membrane. To increase the selectivity of the optimized PVL nanofiber membrane and increase the affinity with ethylene dichloride; the membrane was coated with a dense PDMS/GO layer. The membranes were characterized by SEM, FTIR, contact angle and swelling measurements. Also the membrane performance in ethylene dichloride separation and its separation factors versus temperature (30â70° C) was evaluated. Results show that with increasing temperature up to 70° C, the total flux and the separation factor of (PDMS/GO)/PVL simultaneously increase from about 113 to 191 g/(m2h) and from 3.4 to 11.65, respectively.
