摘要：
Homopolymerization of 3, 4-ethylene dioxythiophene (PEDOT) and copolymerization with N,N-dimethyl aniline (PDMA) were performed onto a platinum electrode. The synthesis was performed using potentiodynamic electrodeposition modes from LiClO4 solution containing 1:1 monomer ratio, in case of copolymer. The influence of sodium dodecyl sulphate (SDS) as a wetting agent was studied. The resulting copolymer films were characterised using cyclic voltammetry and EIS measurements in neutral phosphate buffer solutions. The results confirmed the obtainment of a new material by copolymerizing 3,4-ethylene dioxythiophene with N,N-dimethyl aniline with different properties than the corresponding homopolymers. SEM measurements showed that SDS surfactant had a marked influence on the films porosity. The specific capacitance of the PEDOT-PDMA copolymer was calculated and it showed good stability during cycling in PBS solution.
