Preparation and Characterization of BaTiO3/ PVDF Inorganic-Organic Composite Ultrafiltration Membranes
Abstract.BaTiO3-PVDF(polyvinylidene fluoride) composite ultrafiltration membranes were prepared by a phase separation method.The surface and cross-section of the membranes were investigated by atomic force microscopy and scanning electron microscope.The results showed that the morphology of PVDF membrane can be disturbed by BaTiO3.Albumin bovine serum retention and the water flux of the blend membrane increase.The phenomenon is discussed in terms of the modification of spongy layer and finger-like structure in the blend polymer.
