AgCl nanoparticles were obtained in the reverse microemulsion using styrene and methyl methacrylate mixture as an oil phase. And then, polymer emulsion containing AgCl nanoparticles was obtained through in-situ polymerization of oil monomers in the microemulsion. Finally, polyvinylidene fluoride(PVDF) blending hybrid membranes containing AgCl nanoparticles were constructed by blending method. The results from the structural characterization and ultrafiltration experiments, such as UV-visible spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM), showed that the addition of some polymer emulsion combined with hydrophilic polymer and AgC1 nanoparticles with hydrophilic surface did not only improve the porosity and average pore size of the PVDF blending hybrid membranes, but also enhanced the polarity and hydrophilicity of the hybrid membranes, thus increasing the water flux and antifouling performance of the membranes. However, the addition of excess polymer emulsion could not blend uniformly with PVDF. Moreover, AgCl nanoparticles would form agglomerates in the membrane to clog the membrane pores. Thereby, the water flux and antifouling performance of the membranes were both weakened.
