Аннотация:Conductive polymers such as polyaniline (PANI) and poly-3,4-ethylenedioxythiophene (PEDOT) were prepared by electrochemical polymerization of aniline and 3,4-ethylenedioxythiophene (EDOT), respectively, in the presence of sulphonated polyelectrolytes with different structure and different molecular weight. The aniline and EDOT electropolymerization was performed in potentiostatic (PS), galvanostatic (GS) and cyclic voltammetry (CV) regimes. To elucidate the role of polyelectrolyte in the synthesis we have performed in situ Raman and UV-Vis spectroscopy studies during aniline and EDOT electropolymerization. The films obtained were characterized by cyclic voltammetry, Vis-NIR and Raman spectroelectrochemistry and AFM-microscopy. The dependence of polymer properties and character of the synthesis on polyelectrolyte structure and its molecular weight is discussed considering peculiarities of the aniline and EDOT distribution in the solution of polyelectrolyte with different hydrophilicity, conformational state and spatial distribution of sulfonic groups in polyelectrolyte coils.
