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 (30−70° 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.}, number={2}, journal={International Journal of Industrial Chemistry}, publisher={OICC Press}, author={Nasab, Samira Safaei and nodeh, Ali Arasteh and Khosroyar, Susan and Mahrod, Mahmod Reza Khadangi and Hakimzadeh, Vahid}, year={2024}, month={Jan.}, keywords={Selectivity, Electrospinning, Poly valerolactone, Polydimethylsiloxane} }
