- Аннотация: Abstract—The electrochemical properties of a polymer coating based on the triphenylamine derivative4,4',4"-tris(N,N-diphenylamino)triphenylamine (TDATA) and a composite material obtained in situ by oxi-dative polymerization of TDATA in the presence of single-walled carbon nanotubes (SWNT) PTDATA–15 wt % SWNT applied to graphite foil (GF) were studied. The preliminary anode treatment of the startingGF significantly improves the adhesion of the polymer and composite films to the substrate surface andallows the creation of electroactive polymer coatings by casting stable dispersions of the polymer and com-posite in formic acid. The results of studies by cyclic voltammetry (CV) and charging-discharging curves ofthe PTDATA and PTDATA–15 wt % SWNT on activated graphite foil (AGF) were compared with the datafor the Ni/PTDATA and Ni/PTDATA–15 wt % SWNT electrodes to evaluate the effect of substrates on thecapacity characteristics of the polymer and composite films in an organic electrolyte (1 M LiClO4 in propyl-ene carbonate). The use of modified graphite foil as electric contact leads to a significant increase in the elec-trochemical capacity and stability of the coatings.
