We have synthesized aniline oligomer composites by using heteropoly acid (H4SiW12O40) as a dopant. The doping and dedoping processes of the aniline oligomer composites were investigated with the aid of UV-Vis spectra. The bands of the aniline oligomer at 572 nm weakened or disappeared, and the bands at 268, 412, and 771 nm appeared, after the aniline oligomer was doped. When the solution of the aniline...
A novel synthesis method of polyaniline, solid-state synthesis method, was described. The condition of synthesis was investigated, and polyaniline was examined by the elemental analysis, IR, UV-VIS, XRD spectra. Thermal stability and conducting behavior was studied. Results showed that the best conductivity of the polyaniline doped with H 4 SiW 12 O 40 was 0.3Scm...
