Two types of polyaniline(P1

P2) were synthesized with N

N-dichloro-p-benzoquinone diimine and p-dibromobenzene Grignard reagent using metal Ni (II) complexes as catalyst and through chemical oxidation of aniline respectively. Characterization and performance tests of the copolymers were conducted by Fourier Translation Infrared Spectroscopy (FT-IR)

Ultraviolet and Visible Spectrophotometry (UV-Vis)

Cyclic Votammogram (CV)

charge and discharge analysis

X-ray Diffraction analysis (XRD) and Thermogravimetric Analysis. Results show that the UV-Vis maximum absorption peak of polymer P1 appear at 600nm

while the UV-Vis maximum absorption peak of polymer P2 appear at 443nm. Cyclic Votammogram results indicate that both of the polymers have reversible oxidation-reduction performances

and the p-doped peaks of P1 and P2 appeared at 0.26eV and 0.49eV

respectively.
