Abstract

Abstract: Polyacrylamide(PAM)/montmorillonite(MMT) nano-composite was prepared by in-situ polymerization. Morphology and dispersion of MMT within PAM were investigated by means of TEM. The results show that MMT lamellas exfoliate from PAM matrix. Blend membranes were prepared by ultrasonic dispersion of PAM/MMT and poly(vinyl alcohol)(PVA) solution. The swelling properties of blend membranes in isopropanol aqueous solution and effect of blend ratio, MMT content on separation properties were investigated. The results show that the separation properties of membrane could be improved greatly by adding proper content of MMT nano-particle in PVA.

Key words: Pervaporation, PAM/MMT, Poly(vinyl alcohol), Blend membrane
