Abstract
Conductive Polypyrrole films have been synthesized by electrochemical method in nucleophilic solvent such as N, N-dimetylformamide(DMF), dimethylsulfoxide(DMSO). The effect of protic acid as supporting electrolyte to decrease the nucleophilicity of the solvent was studied. Cyclic voltammetry, I-t transients were carried out to investigate the electrodeposition of conductive polypyrrole film on platinum electrode. Three peaks of 0.65V, 0.85V, and 1.2V vs.
N, N-dimethylformamide(DMF)와 dimethylsulfoxide(DMSO)와 같은 친핵성 용매에 protic acid인 p-toluenesulfonic acid 또는 benzenesulfonic acid를 지지전해질로 사용하여 전도성 polypyrrole 필름을 전해 합성하였다. Cyclic voltammogram을 통해 전기화학적 반응거동을 조사한 결과 0.65, 0.85, 1.12V vs.
