Abstract: Poly (EGDMA-co-VPCA)/SWCNT composite materials were produced on ITO coated glass substrates by surface polymerization method. Physical facilities of the deposits were studied by some techniques and approximation methods such as FTIR, SEM, EDS, MS and EIS. FTIR analyses confirm the formation of poly (EGDMA-co-VPCA)/SWCNT composite film. SEM studies show that the SWCNTs are embedded into the EGDMA-co-VPCA polymer. Semiconducting parameters, such as acceptor density, donor density, flat band voltage, positions of the valence and conduction energy band edge of the poly (EGDMA-co-VPCA)/SWCNT film are obtained by use of the MottSchottky and optical measurements. Mott-Schottky curves show that poly (EGDMA-co-VPCA)/SWCNT composite material exhibits both n-type and p-type conductivity depending on the applied potential. The EIS data were collected from poly (EGDMA-co-VPCA)/SWCNT/ITO/electrolyte system at a frequency range between 0.01 Hz and 300 kHz. Therefore, an equivalent electronic circuit model was fitted to the EIS data or Nyquist data. After the determination of the electronic circuit elements, charge transfer properties between electrolyte and composite polymer are also discussed from the standpoint of solution resistance, charge transfer resistance and constant phase element.
