摘要：

Incorporation of large aromatic sulfonate (AS) into polyaniline emeraldine base form (PANI-EB) was investigated. Geometrical stability of AS-doped polyaniline was confirmed by molecular modeling calculations. The energy storage (ES) (Whkg(-1)) of these polymers depends on the size of the AS and the functional group in the dopant. Cyclic voltammetric measurements showed that the electroactivity of the AS-doped PANI, due to the oxidation/reduction of the first redox only of the salt/base PANI. A good linearity between the cathodic peak height (I-pcl) and the square root of the scan rate (rootv,) more than 0.95 over the range 5-100 mVs(-1) indicate the electron transfer is diffusion controlled.
