Prepare and Performance Research on PVA/TiO2 Composite Films
Polyviny alcohol (PVA)/ Titanium dioxide (TiO2) composite films with diffrernt content of nano- TiO2were prepared by solution casting method. The structure of the film was characterized by FT-IR,and the water tolerance, viscosity, and light transmission rate of composite membrane were tested. The results showed that Nanometer TiO2 had strong hydrogen bonding interaction with PVA molecules, and with the increasing additive amount of nanometer TiO2, water resistance was improved, the viscosity of the composite sol rised, and the rate of UV transmission decreased obviously.
