Abstract

본 연구에서는 수정진동자와 UV/Vis를 동시에 사용하는 새로운 실험법을 소개함과 동시에 그 응용의 예로서 폴리피를 박막의 전기화학적인 산화-환원 반응을 조사하였고, 그 결과 전극 표면에서 일어나는 전기화학적인 메카니즘을 이해하는데 용이함을 알 수 있었다. 본 실험법은 전극/용액 계면 현상을 연구하기 위하여 수정진동자의 분석 변수, 전기화학적인 분석 변수, 그리고 UV/Vis의 분석 변수를 제공하여 전기화학적 물질 전달에 기인한 산화-환원 반응에 의한 전기화학적, 전기화학적 발광, 점탄성 특성, 질량 변화 그리고 광학적 성질 등에 대한 상관 관계를 제시하였다.
In this paper, we introduce a new experiment system of quartz crystal analyzer combined with UV/Vis spectroscopy. As an example of application, the electrochemical redox-process of polypyrrole has been investigated and the system was found to be effective to understand electrochemical mechanism occurred on the electrode surface. The QCA-UV/Vis system can provide plentiful analytical information, for the study of electrode/solution interface phenomena because the system can provide electrochemical, gravimetric and optical variables. In this paper, we suggest analytical relations for investigating the electrochromic, viscolestic property, mass change and optical property of the film due to electrochemical redox-process induced mass transportation.
