초록

Fullerene으로 수식된 PPy(Polypyrrole)전극 즉, graphite(Gr)/ppy, fullerene $(full^-)$항을 Gr/5mM PPy, 1mM $full^-,0.1M\;TBABF_4,\; CH_3CN/Pt$형의 전지로 전기화학 중합법으로 제작하였다. $(full^-)$의 생성속도는 기질전극 재료인 Pt/ppy, Pt, Gr 및 Au전극에 대해 각각 93.6, $7.0\times10^2,\;42.6$ 및 $1.3\times10^2cms^{-1}$였다. 수식되지 않은 Gr/ppy와 수식된 $Gr/ppy, full^-$ 전극에 대한 어드미턴스 값이 $1.7\times10^{-3}S$에서 $8.3\times10^{-3}S$로 5배나 증가하였으며, 전기 이중층의 용량은 $2.4\times10^{-5}\;F$에서 $4.2\times10^{-5}\;F$로 174배 증가하였다.

The type of graphite(Gr)/ppy, fullerene$(full^-)$ electrode, ppy one modified with $(full^-)$, was prepared with the cell type of Gr/5mM ppy, 1mM $(full^-)$, 0.1M $TBABF_4$, CH3CN/Pt. The values of the ionic formation rate of the it at electrode materials such as Pt/ppy, Pt, Gr and Au were $93.6,\;7.0\times10^2,\;42.6\;and\;1.3\times10^2cms^{-1}$ respectively. The admittance values of the Grippy electrode and the modified Grippy, $(full^-)$ one were five times enhanced $1.7\times10^{-3}S\;to\;8.3\times10^{-3}\;S$ and capacitance values of electrical double layer of them were 174 times increased $2.4\times10^{-6}\;F\;to\;4.2\times10^{-5}\;F$ respectively.
