Abstract

It has been proved by the study on nanofiltration with PVA dense membranes in our laboratory that the PVA is good material for the formation of chemically stable nanofiltration (NF) membranes. However, the PVA NF composite membranes prepared so far have rarely shown flux and rejection high enough for the commerciallyzation. The reasons for them would be the relatively thick thickness and improper crosslinking degree of the PVA active layers of the composite membranes. In this study, PVA composite membranes with improved nanofiltration properties have been prepared and characterized in terms of the morphology and permeation properties.
