Synthesis Of AgCl Nanoparticles In Microemulsion And Study Of Organic-Inorganic Hybrid Membranes

In this paper, AgCl/Poly(GMA-MMA-AMPS) organic-inorganic hybrid membranes were prepared via reverse microemulsion polymerization, with GMA(Glycidyl Methacrylate)+MMA(Methyl Methacrylate) as oil phase, NaCl and AgNO3 aqueous solution as water phase, polymerizable AMPS(2-Acrylamido-2-Methyl Propane Sulfonic Acid) as surfactant.The exploratory research on reverse microemulsion stability, hybrid membranes morphology and the effect on the separation of benzene/ cyclohexene.GMA+MMA microemulsion stability was analysed through the measurement of conductivity,the results showed the stable reverse microemulsion system could be obtained in the case of CAMPS=0.2-0.6mol/L, Csalt=0.1-0.5mol/L andω(nH2O/nAMPS)＜20.The growth of AgCl nanoparticles were investigated by UV-Visible absorption spectra. Furthermore, the diameter size distributon and shape of the nanoparticles were characterized by TEM (Transmission Electron Microscope). The results revealed that all the AgCl nanoparticles in GMA+MMA microemulsion were sphere-like, the diameter was 50nm or so and its distribution was relatively narrow. The amount of AgCl nanoparticles increased with the growth ofω,CAMPS and concentration of salt (CNaCl,CAgNO),the diameter size decreased or almostly maintained the same.The SEM(scanning electron microscope) showed that the mean diameters of AgCl nanoparticles are small (50nm or so); EDX showed AgCl nanoparticles maintained well dispersion in AgCl/poly(GMA-MMA-AMPS) copolymer organic-inorganic hybrid membranes.The results of pervaporation indicated that the hybrid membrane has well pervaporation properties, which could overcome the trade-off phenomenon of polymer membranes with appropriate CAMPS,Csalt,ω.
