Abstract: The TiO₂@Ag/polyvinylidene fluoride(PVDF) composite membranes with different Ag contents were prepared by photochemical reduction deposition and solution scraping methods. The physical properties and photocatalytic properties of the TiO₂@Ag/PVDF composite membranes were analyzed by electronic universal material testing machine, UV-visible near-infrared spectrophotometer, XRD and so on. The results show that compared with pure TiO₂/PVDF composite membranes, the tensile strength of TiO₂@Ag/PVDF composite membranes is obviously increased but the breaking elongation is decreased, and TiO₂@Ag/PVDF composite membranes can promote the response spectral range of TiO₂ to visible region. Furthermore, the photocatalytic degradation abilities of the TiO₂@Ag/PVDF composite membranes increase at first and then decrease with the increase of loaded Ag. Moreover, the TiO₂@Ag/PVDF composite membranes have excellent reusability and self-cleaning effect in visible right. Above all, the TiO₂@Ag/PVDF composite membranes prepared by the experiment can satisfy the needs of practical applications. The TiO₂@Ag/PVDF composite membranes loaded with Ag have a significant potential foreground in photocatalytic degradation field.
