摘要：

Dual type polymer electrochromic devices (ECDs) based on potentiodynamically coated films of octanoic acid 2-thiophen-3-yl-ethyl ester (OTE), decanedioic acid bis-(2-thiophen-3-yl-ethyl) ester (DATE) and ethylene dioxythiophene (EDOT) were constructed. The former two function as anodically coloring layers and the latter as a cathodically coloring layer in between tetrabutylammonium tetrafluoroborate (TBAFB) poly(methylmethacrylate) gel media. The spectroelectrochemistry, switching ability and stability of the devices were investigated by U-V-Vis spectrometry and cyclic voltarnmetry. These devices exhibit low switching voltages (0-1.4 V) and short switching times with reasonable switching stability under atmospheric conditions. (C) 2004 Elsevier B.V. All rights reserved.
