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.
