| Abstract: | The authors used sol - gel method to prepare nano - sized TiO2 sol, then polyvinylidene fluoride （PVDF） / TiO2 composite membranes were prepared by coating method. The influence of TiO2 concentration on the separating performance of the composite membranes were investigated and the structure of the composite membranes were studied by X - ray diffraction （XRD） and FT - IR spectrum （ FT - IR）. |
