The hydrophobic microporous membranes were prepared from a blend system by thermally induced phase separation (TIPS) process. The polymer blend system was isotactic polypropylene (iPP)/ high-density polyethylene (HDPE) and the diluent was soybean oil. The effects of the mass ratio of iPP and HDPE and the initial concentration of blending on the membranes structure were both investigated. Additionally, the influence of the feed temperature and the feed rate on the VMD performance of iPP/HDPE blend membranes was also investigated. For 0.5M aqueous NaCl solution, the VMD flux and reject ratio of the membranes reached 8.7kg/(m2·h) and nearly 100% under the optimum conditions (mass ration of iPP/HDPE was 6:1, and intial blend concentration was 38%), respectively.
