| Abstract: | The conductive form of polyaniline was synthesized by the anodic and chemical oxidation of aniline in malonic acid medium. The conductivity of polyaniline doped with malonic acid changed from 1.62×10–6 to 2.5×10–5Scm–1 depending on the way it was synthesized. The polymer growth rate was observed to be very slow in malonic acid compared with H2SO4. Thermogravimetric data revealed that the maximum thermal reaction rate of PANI doped with malonic acid was at 200°C and 520°C compared with 290°C and 530°C of the polymer doped with H2SO4. |
