Abstract: In this paper, by polymeric electrolyte(PMMA-PC-EC-LiClO4), we introduced CeO2-TiO2 composite as the complementary electrode of a new solid-state dual-type polyaniline electrochromic device(ECD). The electrochromic performance of the dual-type ECD was characterized using in situ UV-Vis spectroscopy. Compared to single-type ECD(ITOPANIPEITO), the dual-type ECD showed better electrochromic performance such as less response time, longer cyclic lifetime. Also, the composition of the electrolyte was found to influence the cyclic stability of PANI. The optimized dual-type ECD exhibited reversible electrochromic behavior from yellow at bleached state(-1.5 V) to blue at colored state(1.0 V PANI vs. CeO2-TiO2) with good cyclic stability. The transmittance of the ECD at 700 nm changed from 42.19% to 13.35% with a coloration efficiency of 152.1 cm2/C.

Key words: Polyaniline, CeO2-TiO2 composite, Electrochromic device
