PREPARATION AND PROPERTIES OF ACRYLONITRILE MALEIC ANHYDRIDE GRAFT POLY(VINYL ALCOHOL) ELECTROCONDUCTIVE MEMBRANE

摘要

Acrylonitrile (AN) and maleic anhydride (MA) were grafted onto PVA to form PVA-g-AN/MA membrane, which was reacted with different metal salts. PVA-g-AN/MA metal chelated films were prepared by the mixing and soaking methods. The electroconductivity of the resulting films was investigated. The amidoxime group was introduced into the PVA-g-AN/MA film under various conditions, in order to increase the amount of ions adsorbed in the soaking method. [References: 17]
