The main direction of the research of the scientific group is focused at the electrochemical synthesis and investigation of the properties of conducting organic polymers, redox polymers and composite materials based on them, obtained as thin films or phase layers on the electrode surface. In recent years, experimental and theoretical studies have been focused on the development of scientific and technological fundamentals for obtaining new electrode materials, studying the kinetics and mechanism of solid-phase charge transfer processes in such materials. Composite electrode materials based on organic conducting polymers of thiophene series, mainly poly-3,4-ethylenedioxythiophene and inorganic compounds (rechargeable oxides and other compounds of transition metals, noble metal nanoparticles) are studied.

Metal-polymer nanocomposite materials, developed by the group, are promising for application in a number of fields of science and technology, in particular, as energy-intensive electrode materials for the development of new energy-saving devices (batteries, supercapacitors), as catalysts for important electrochemical processes in fuel electrochemical cells and sensors, and also as electrochromic coatings.

To study the electrochemical properties of materials, methods of cyclic voltammetry, rotating disc electrode, spectroelectrochemistry, galvanostatic charge-discharge, electrochemical quartz microgravimetry, and electrochemical impedance spectroscopy are used. The composition and structure of materials are studied using X-ray diffraction analysis, X-ray photoelectron spectroscopy, scanning and transmission electron microscopy, IR spectroscopy, electronic absorption spectroscopy, and other methods.
