Preparation and Characterization of TiO(2)/g-C(3)N(4)/PVDF Composite Membrane with Enhanced Physical Properties
TiO(2)/g-C(3)N(4)/PVDF composite membranes were prepared by a phase inversion method. A comparison of the performance and morphology was carried out among pure PVDF, g-C(3)N(4)/PVDF, TiO(2)/PVDF and TiO(2)/g-C(3)N(4)/PVDF composite membranes. The results of permeability and instrumental analysis ind...

description | TiO(2)/g-C(3)N(4)/PVDF composite membranes were prepared by a phase inversion method. A comparison of the performance and morphology was carried out among pure PVDF, g-C(3)N(4)/PVDF, TiO(2)/PVDF and TiO(2)/g-C(3)N(4)/PVDF composite membranes. The results of permeability and instrumental analysis indicated that TiO(2) and g-C(3)N(4) organic-inorganic composites obviously changed the performance and structure of the PVDF membranes. The porosity and water content of 0.75TiO(2)/0.25g-C(3)N(4)/PVDF composite membranes were 97.3 and 188.3 L/(m(2)·h), respectively. The porosity and water content of the 0.75TiO(2)/0.25g-C(3)N(4) 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. |
