Abstract：

This article studied the impact of inorganic nanoparticles, ZnO/Al2O3/ TiO2/SiO2, on share viscosity of polyvinyl chloride (PVC)/polyether sulfone (PES) blend system. Then tested the characters of the nanoparticle modified membranes, including shear viscosity micro-structure (SEM), water flux, rejection rate, hydrophilic and mechanical property. The result showed, all nanoparticles made the surface pore diameter small and compact. The larger shear viscosity of casting solution and membrane pore rate, the greater the water flux. Addition, nanoparticles improved the BSA rejection and mechanical property in different degrees.
