Abstract
Nano-TiO2was modified with amino propyl triethoxy silane (KH550). The PVA/nano-TiO2composite film was formed through a solution casting method. Nano-TiO2and the composite film were characterized and the results show that the PVA/nano-TiO2composite prepared by direct-blending method has better dispersibility and lower weightlessness than the unmodified PVA/nano-TiO2. The tensile strength of the PVA/nano-TiO2composite was increased by 66.35%. The coefficient of the moisture permeability and permeability coefficient of the PVA/ nano-TiO2composite were decreased by 29.94% and 56.67%, respectively.
