Resumo
The electrochemical properties of a polymer coating based on the triphenylamine derivative 4,4′,4″-tris(N, N-diphenylamino)triphenylamine (TDATA) and a composite material obtained in situ by oxidative 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 starting GF significantly improves the adhesion of the polymer and composite films to the substrate surface and allows the creation of electroactive polymer coatings by casting stable dispersions of the polymer and composite in formic acid. The results of studies by cyclic voltammetry (CV) and charging-discharging curves of the PTDATA and PTDATA—15 wt% SWNT on activated graphite foil (AGF) were compared with the data for the Ni/PTDATA and Ni/PTDATA—15 wt% SWNT electrodes to evaluate the effect of substrates on the capacity characteristics of the polymer and composite films in an organic electrolyte (1 M LiClO4 in propylene carbonate). The use of modified graphite foil as electric contact leads to a significant increase in the electrochemical capacity and stability of the coatings.
