Abstract: A method is presented for obtaining thin-film mesoporous coatings for protective glasses in nano- and optoelectronic devices for various purposes, including: obtaining titanium oxide sols with the addition of silver nitrate, applying coatings by the “dipcoating” method with further heat treatment. The kinetic constants of Smoluchowski's fast and slow coagulation and the activation energy of the process at various concentrations of silver nitrate were calculated. The optimal concentration of silver nanoparticles in the ash was determined by the least squares method.

Keywords: mesoporous coatings, composite material, sol-gel method, nanoparticles, titanium dioxide, silver, coagulation constant
