ABSTRACT:
An organically modified sol-gel method of preparing substantially crack-free aluminosilicates films is provided. Chelated aluminum alkoxide and polydimethylsiloxane are mixed in a 1:1 ratio by weight in a solvent and refluxed at approximately the boiling temperature of the solvent to produce a sol-gel liquid including polymerized aluminosilicates. The sol-gel liquid is cooled to room temperature. Additional solvent is added to the sol-gel liquid to reduce its viscosity. A substrate is coated with the reduced viscosity sol-gel liquid. The coating of sol-gel liquid on the substrate is dried to produce an organically modified aluminosilicates sol-gel film. The sol-gel film is heated, to enhance polymerization of the sol-gel film and to evaporate residual solvent, and then cooled.
