In Situ Optoelectrochemical Approach for the Dynamic Property Study of Polypyrrole Thin Film by Quartz Crystal Combined with UV‐Visible Advanced Design

Abstract

We have designed a new experiment system composed of quartz crystal analyzer (QCA) and UV‐visible (UV‐vis) spectroscopy. As an example of an application, the redox process of polypyrrole was investigated and it was easy to understand the electrochemical mechanism occurring on the electrode surface. The QCA‐UV/vis system can provide plentiful analytical information for the study of electrode‐solution interface phenomena. In this paper we suggest eight analytical relations for investigating the electrochromic and viscoelastic property change due to electrochemical mass transport that occurs during the redox process of polypyrrole. © 1999 The Electrochemical Society.
