INVESTIGATION OF THE FORMATION OF ELECTROCHROMIC WO 3 FILMS ON THE SURFACE OF AN ITO-ELECTRODES BY THE METHOD OF CHRONOAMPEROMETRY Shchegolkov A.V., researcher, researcher-teacher, e-mail: alexxx5000@mail.ru Tambov State Technical University, 106 Sovietskaya st., Tambov, Russian Federation Abstract Recently, in the Russian Federation and abroad, the method of electrochemical deposition of metal coatings (films) on the surface of electrically conductive products has been increasingly used in order to obtain functional, protective and operational properties, such as: anti-corrosion, antibacterial, radio-absorbing, light-absorbing, etc. in particular electrochromic films WO 3 for obtaining photoelectric coatings for optical switches modulating light radiation, i.e., for “smart” windows, various sensors with high adhesion. In this work, the technique of obtaining electrochromic WO 3 films by cathodic electrodeposition on the surface of a PET / ITO electrode is considered, various factors that affect the formation of WO 3 films, such as the shape of the current, the concentration of the solution. The process of formation of electrochromic WO 3 films obtained on the surface of the ITO-electrode is studied by the method of chronoamperometry. Keywords Electrochromic WO 3 film, electrochemical deposition, chronoamperometry.
