脉冲电泳沉积制备电致变色WO3薄膜
Preparation of electrochromic WO3 films by pulsed electrophoretic deposition
摘要
Abstract
The process parameters employed for the pulsed electrophoretic deposition of WO3 films were optimized by the orthogonal design method. The eloctrochromic properties of the WO3 films prepared under the optimized condition were studied through characterizing the microstructure, transmission spectra and cyclic voltammogram of the films. The optimal process parameters for the pulsed electrophoretic deposition of WO3 films are: average current density = 0.2× 10-3 A/cm2,deposition time = 6 min, duty cycle = 75% and pulse period = 10 ms. For the WO3 films prepared under the optimized condition, they are amorphous film with a thickness of about 251 nm, their transmission modulation (△T) reaches 76%~80% in the visible region (550~800 nm), and they exhibit high electrochemical activity with an ion storage capacity of 27.8× 10-3 C/cm2; However, their bleaching/coloring responses are asymmetric and reversibility is relatively low (75.1%).关键词
