Paper Abstract

Silica antireflective films were prepared on flat glass substrates by spraying method. By adding n-propanol, isopropanol, n-butyl alcohol and low vapor pressure solvent 1,3-butanediol to form gradient volatilization solvents, the “whitish” in color of coating was solved. Spray coating is a single side coating technology which is suitable for flat or weakly bent substrates. This method can be flexibly applied to single-side coating, double-side heterogeneous coating and rapid coating of large-scale components. The results show that the antireflection coating prepared by spraying method has good optical properties, the transmittance can reach 99.61%, the root mean square roughness is 1.22 nm and the uniformity of the coating was smooth. The spraying method has been successfully applied to the preparation of antireflection films on flat substrates.
