摘要：

制备了基于聚3-甲基噻吩(P3MeT)和聚苯胺(PANI)的两种结构(侧面结构和垂直结构)固态导电聚合物多色电致变色器件(ECD). 采用电化学现场紫外-可见光谱法研究了侧面结构固态ECD的电致变色特性, P3MeT-ECD显示出蓝色和红色的可逆变化, PANI-ECD显示出墨绿色和黄绿色的可逆变化, 同时采用P3MeT和PANI作变色材料的P3MeT-PANI-ECD可以实现红、蓝、墨绿和草绿多色变化. 用激光雕刻微型化P3MeT-PANI变色层组装制得的侧面结构固态P3MeT-PANI-ECD控制合适电压也可多色变化. 另外, 用CeO₂-TiO₂作为P3MeT-PANI对电极的垂直结构固态P3MeT-PANI-ECD在实现红、蓝、墨绿和草绿多色变化的同时, 也可进行四色自由搭配选择.

Abstract:

Multicolor solid-state electrochromic devices(ECD) based on conductive polymer[poly(3-methylthiophene)(P3MeT) and polyaniline(PANI)] were constructed in two kinds of configuration: lateral and vertical. The electrochromic performance of the laterally configured ECD was characterized by in-situ UV-Vis spectroscopy. P3MeT ECD shows blue-red reversible changes, and PANI-ECD shows darkgreen-yellowgreen reversible changes. The laterally configured P3MeT-PANI-ECD which employed both PANI and P3MeT as electrochromic layer exhibits darkgreen-yellowgreen-blue-red multicolor changes. ECD miniaturized by laser engraving also exhibits multicolor changes. Introducing CeO₂-TiO₂ as the complementary electrode, the vertically configured P3MeT-PANI-ECD can show four colors freely.
