Paper Title:
Mixed Matrix Membranes from Crosslinked Poly(vinyl alcohol)(PVA) Composited with Zeolite 4A Grafted with Poly(2-hydroxyethyl methacrylate)(zeolite-g-PHEMA)
  Abstract

The mixed matrix membranes were prepared from crosslinked PVA embedded with zeolite 4A that was grafted with PHEMA. The PHEMA was grafted onto the zeolite surface by first, attaching the vinyl-silane onto the zeolite surface and subsequently polymerizing HEMA monomer via the free-radical polymerization. The FT-IR spectroscopy confirmed the successful grafting of PHEMA on the zeolite. The grafting percentage determined by thermalgravimetry analysis (TG) was found to increase with the amount of HEMA monomer. The membrane swelling in water and pure acetone revealed the decreasing trend with increased the zeolite loading. Examined by DSC, the amount of non-freezing bound water decreased with increasing the zeolite in the membranes.
