Abstract: The title PVA/SiO2 hybrid materials with different silicacontent are prepared through the sol-gel process using TEOS and PVA, which are applied onto the transparentmaterials as anti-fogging coatings. Analysis by FT- IR has show n the forming of bond of Si-O-Si and remains of OH group. Its transmittance is measured by use of spectrometor. The anti-fogging property, hardness and water- resistant property of the hybridmaterial at different silica content are discussed.
