Anti-glare,anti-static thin film and transparent conductive film are widely used in many fields of production, science and technology, such as solar cell,TV image display panel, instrument panel and transparent electrode. Anti-glare and anti-static double-layered coating on ordinary glass prepared by a sol-gel technique is introduced. The outer layer of low refractive index is coated on high refractive index inner layer. The main composition of outer layer is SiO@sub 2@. Some SnCl@sub 4@ added into this film increases the conductivity of this film. The latter can be replaced by other hygroscopic metal salts,such as Al(NO@sub 3@) @sub 3@,AlCl@sub 3@,ZnCl@sub 2@, etc.. The inner layer is composed of TiO@sub 2@ and SiO@sub 2@. The glass panel with the double-layered coating shows the resistivity of 10@super 9@ @OMEGA@/square and reflectance of 1.6 % which is reduced to one-fourth of that without coating. A transparent film with high conductivity on ordinary glass panel prepared by a sol-gel technique is also introduced. This Sb-doped SnO@sub 2@ film is made from alkoxide which was previously prepared in our lab. This ATO film has a polycrystall structure. The resistivity of the ATO film has minimum value of 10@super 3@ @OMEGA@/square while the doping level of the solution is about 7%. Finally,factors such as enviromental temperature and humidity,coating technology,effecting the characteristics of these films are discussed.
