Popis:	TiO2/g-C3N4/PVDF composite membranes were prepared by a phase inversion method. A comparison of the performance and morphology was carried out among pure PVDF, g-C3N4/PVDF, TiO2/PVDF and TiO2/g-C3N4/PVDF composite membranes. The results of permeability and instrumental analysis indicated that TiO2 and g-C3N4 organic-inorganic composites obviously changed the performance and structure of the PVDF membranes. The porosity and water content of 0.75TiO2/0.25g-C3N4/PVDF composite membranes were 97.3 and 188.3 L/(m2·h), respectively. The porosity and water content of the 0.75TiO2/0.25g-C3N4 membranes were increased by 20.8% and 27.4%, respectively, compared with that of pure PVDF membranes. This suggested that the combination of organic-inorganic composite with PVDF could remarkably improve UTS, membrane porosity and water content.
