초록
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.
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.
