Abstract

When butyl rubber dissolved in toluene was used as a binder of carbon powder, carbon paste showed a mechanical hardness due to the fast volatility of the solvent just after the electrode fabrication. With a view of validating its quantitative electrochemical behaviors, its kinetic parameters, e.g. the symmetry factor, the exchange current density, the capacity of the double layer, the Michaelis constant, the time constant and other factors were investigated. Our experimental facts indicated that butyl rubber is available for a promising binder of carbon powder.

톨루엔에 녹인 부틸고무 용액을 탄소가루의 결합재로 사용하였을 때, 탄소반죽은 용매 증발 후 기계적 경도를 보였다. 고무 용액의 이런 성질을 이용하여 닭의 간조직이 혼입된 새로운 과산화수소 정량 효소전극을 제조하였다. 그것이 전기화학적으로 정량적 행동을 보이는지 확인하기 위하여 그것의 전기화학적 파라메타 즉 이중층의 대칭인자, 교환전류밀도, 축전용량, Michaelis 상수 및 시간상수 등을 도출하였다. 실험 결과는 부틸고무 용액이 탄소가루의 결합재로 활용될 수 있음을 보여 주었다.
