5-dimethoxyaniline) (PAN/PDMA) composite film with high adhesion strength

uniform and excellent cyclic voltammetry were synthesized by cyclic voltammetry on ITO glass. The effect of scan rate on the shape and cyclic voltampere characteristics of PAN film

PDMA film and PAN/PDMA composite film were discussed. The chemical structure and AC impendence was characterized respectively by FTIR

UV-Vis and EIS. The results showed that the optimum scan rate of PAN film

PDMA film and PAN/PDMA composite film were 10mV/s

10mV/s and 100mV/s

respectively. The adhesion

surface uniformity

density degree

cyclic reversibility and electrode capacitance of the composite film are better than that of the two films. PAN and PDMA homopolymerization chains were bonded by chemical bonds and the conjugated degree of macromolecular chains in PAN/PDMA composite film was apparently higher than that of pure PAN chain when aniline and 2

5-dimethoxyaniline copolyed. The AC impendence of PAN/PDMA composite film was lower than that of the two films.
