In this study, novel asymmetric membranes with pre-selective layer consist of electrospun poly(vinyl alcohol) (PVA) nanofibres and electrospun PVA nanofibres integrated with two different types of hydrophilic fillers i.e. micron-si .ed copper benzene-1,3,5-tricarboxylate (Cu BTC) and nano-sized carboxyl multi-walled carbon nunotube (COOH-MWCNT), respectively were successfully fabricated. The existence of olectro pun hydrophilic nanofibre layer was observed to significantly improve the separation performance by serving as a hydrophilic pre selective barrier during the application of all the asymmetric membranes to the pervaporation dehydration of aqueous 1,4-dioxane solutions. Aftor th addition of the hydrophilic fillers, both electrospun Cu-BTC/PVA (Mcuerc) and COOt l MWC'NT/PVA (McooH-MwcNr) membranes exhibited enhanced separation performance comp t d to electrospun PVA (Mo) due to increased hydrophilicity of the pre-selective layer.
