The compatibility of polyvinylidene fluoride(PVDF) and polyacrylonitrile(PAN) has been investigated. The influence of the compatibility of the blend solution and casting technology on the membrane properties has been examined. The results showed that the PVDF/PAN ultrafiltration membrane made from homogeneous and clear casting solution of blend possessed fairly great flux and high retention ratio and the membrane morphologically consisted of uniform finger-like holes.
