For improving the hydrophily and the anti-fouling performance of the polyvinylidene fluoride (PVDF) membrane, the PVDF/polymethyl methacryla (PMMA)/polyether sulfone (PES) blend membrane is prepared by the immersing precipitation. It is shown that the ternary system has a good compatibility when the ratio of PVDF/PMMA/PES is 85:10:5, 80:15:5, 75:15:10 and 70:20:10. Additionally, the hydrophilicity of those membranes is improved. The optimized PVDF/PMMA/PES blending ratio is 70:20:10. Under this condition, the water flux is 43 L·m-2·h-1, the porosity is 73%, the advancing contact angle is 75.88°, and the receding contact angle is 20.22°.
