Growth and Properties of Poly-o-Aminophenol Films with Three Dimensional Combination of in Situ Electrochemical Quartz Crystal Microbalance and Fourier Transform Infrared Spectrolectrochemisty

A three-dimensional combined technique,in situ quartz crystal microbalance in combination with infrared spectroscopy and electrochemistry was proposed.With this combining technique,the depositing process of poly-o-aminophenol on gold electrode surface was monitored.The oxidation and polymerization of the o-aminophenol as well as the electrochemical properties of poly-o-aminophenol in acidic solution were investigated.Information about mass coverage of polymer,ion doped/de-doping process and change in structure of the polymer were obtained simultaneously and discussed.The results indicated that this method could be widely applied to investigate electrode-surface-relevant processes.
