Description

technical field [0001] The invention relates to a copper phthalocyanine / polyaniline composite film and a preparation method thereof. The composite film prepared by the method can be applied to electrochromic devices. Background technique [0002] Electrochromic (EC) can be divided into inorganic EC materials and organic EC materials according to different materials; inorganic electrochromic materials mainly include WO 3 、TiO 2 , NiO, etc. have good photochemical stability, but inorganic electrochromic materials have a single color, and most materials can only switch between two colors; the discoloration speed is slow, generally within a few seconds or even ten seconds; Compared with color-changing materials, organic electrochromic materials are favored by people because of their easy structure modification, various types and high optical contrast. [0003] The application of metal phthalocyanine compounds in photoconductivity is also relatively common. As photoconductive ...
