In comparison, two types of working electrodes show different i-t curve during electrodepostion. One of these working electrodes is attached by electrostatic film, and the other one is not. Experiment is executed by constant potential for different time. The resultant micropattern of Prussian Blue have been characterized by means of Optical microscope (OM), Scanning Electron Microscope (SEM) and Surfcorder analysis. The selectivity of micropattern defined formula as ΔH/Tt×100%, where T is thickness of Prussian Blue film, ΔH is concave micropattern of height. In this study, It is found that with the same electrodeposition time, micropatterned thin films possess that electrochromic properties superior to the thin films without micropatterns. Therefore,impedance analysis of electrochemical impedance spectroscopy for electrochromic thin films has been carried out in the study.And will obtain Rs,Rct of impedance value. It is found with the charge transfer resistance values, micropatterned thin films possess that was also lower than the thin films without micropatterns.
