全固态聚苯胺-二氧化钛电致变色器件的制备
Preparation of all solid-state electrochromic device based on polyaniline-titanium dioxide
摘要
Abstract
The all solid-state electrochromic devices with symmetrical structure (SSECD, ITO‖PANI‖electrolyte ‖PANI‖ITO) and asymmetric structure (ASECD, ITO‖PANI‖electrolyte‖TiO2‖ITO) were prepared by using polyaniline (PANI)as the electrochromic material. Titanium dioxide thin films were prepared by pulling method, and after treated at 500 C, the titanium dioxide thin film formed by particles of magnitudes 10～20 nm and the thickness about 200 nm was found presenting as the typical anatase structure and having a good charge storage capacity as well. The in-situ electrochemical UV-visible spectroscopy comparative investigations find that the maximum transmission rate difference(photonic ratio) of ASECD is 43.3％, nearly about twice of SSECD. Besides, ASECD takes on reversible color variation among yellow (-1.4 V), green (0 V)and blue (1.4 V), and has faster coloring/fading response time(0.8 s), can be developed in practical utility.关键词
