Improvement of Permselectivity of Microphase-separated Membranes for Removal of Volatile Organic Compounds

摘要

It is very important for our living to remove environmental hormones such as aromatic and chloriated hydrocarbons from waste water.In this study,poly(methyl methacrylate)-graft-poly(dimethyl siloxane) (PMMA-g-PDMS) membranes,which have shown high benzene-permselectivity in pervaporation (PV),were surface-modified with fluorine-containing polymer additives and modified with tert-butyl calix [4] arene (CA) in order to improve the benzene-permselectivity,and the relationship between the membrane surface structure and the permselectivity is discussed.
