Abstract：TiO2 membrane was prepared by sol-gel method through using tetrabutyl titanate as the precursor, PEG as an additive. Thermal stability, crystal phase change, specific surface area, pore structure, surface morphology, and hydrophilicity of the membrane were characterized by means of TG-DTG, XRD, BET, SEM and contact angle analysis etc. The results show that,with the increase of PEG2000 content, the temperature of TiO2 membrane anatase crystal transformed into rutile crystal increases, the surface of membrane develops from dense and smooth to cracking and course, the specific surface area continues to increase and the average pore size decreases, the contact angle increases from 3° to 20.2°. When the PEG2000 content is 5%, TiO2 membrane has the best performance and super hydrophilicity.
