| Abstract: | SnO2/PI composite films were composed with ployimide as substrate and SnCl2 as precurosor via surface modification and ion-exchange method.The optimal preparation conditions were discussed.And the morphology,structure of the composite films were characterized by SEM-EDS,ATR-FTIR and XRD.The photocatalytic activity ware evaluated by photocatalytic degradation of the concentration loss of MB.The photocatalyst degradation rate of MB was 98.6%after 6h. |
