Abstract

Abstract: Nanoparticles of AgCl were synthesized in W/O microemulsion using 2-acrylamido-2-methyl propane sulfonic acid (AMPS) as surfactant, glycidyl methacrylate(GMA)/ methacrylate(MMA) mixture as oil phase. And then AgCl/poly(GMA-MMA-AMPS) copolymer organic-inorganic hybrid membranes were prepared by microemulsion polymerization for separation of benzene/cyclohexane mixture by pervaporation. The effect of oncentration of surfactant(CAMPS) and salt (CNaCl 、CAgNO3) on formation and morphology of AgCl nanoparticles were studied by ultraviolet-visible spectrum and transmission electron microscopy(TEM). The results shown that the mean diameters of AgCl nanoparticles are small (10-30nm); the sizes of AgCl nanoparticles increased with ω and concentration of salt (CNaCl、CAgNO3). AgCl nanoparticles maintained well dispersion in AgCl/poly(GMA-MMA-AMPS) copolymer organic-inorganic hybrid membranes. The hybrid membrane demonstrated good separation performance for pervaporation of benzene/cyclohexane mixture, and could overcome the trade-off phenomenon of polymer membranes.

Key words: W/O microemulsion, AgCl nanoparticle, organic-inorganic hybrid membrane, pervaporation
