The application of titanium dioxide coatings by the extraction-pyrolysis method

Abstract

The extraction-pyrolytic method of applying a TiO₂ film coating has been considered. The coating is suitable for various applications, in particular as a coating for self-cleaning glass, photocatalytic sterilization for medical and microbiological purposes, solar energy, and automotive and construction industries. Advantages of this method are its low cost and the possibility of coating large surfaces. The processes of extraction of titanium(IV), application of films of organic extracts to substrates, and pyrolytic treatment of precursors have been described. The phase composition and microstructure of the coatings obtained have been studied. It has been shown that the application of solutions of organic extracts to glass and metal substrates contributes to the formation of nanostructured continuous films, which possess photocatalytic activity.
