Scanning electrochemical microscopy in combination with piezoelectric quartz crystal impedance analysis for studying the growth and electrochemistry as well as microetching of poly(o-phenylenediamine) thin films

A new scanning electrochemical microscopy (SECM) with piezoelectric quartz crystal impedance(PQCI) combination method was demonstrated. This method can provide useful multidimensional information for studying the cyclic voltammetric growth of poly(o-phenylenediamine) thin films at gold electrodes in acidic, neutral, and alkaline aqueous solutions and the microetching of these films.
