Dual-type polymer electrochromic devices based on [(3-thienyl)methylmethacrylate]-co-[p-vinyl benzyloxy poly(ethylene oxide)]/polythiophene and thiophene-capped poly(ethylene oxide)/polythiophene and ethylene dioxythiophene were constructed via electropolymerization. Spectroelectrochemistry, switching ability and stability of the devices were investigated using UV-visible spectrophotometry and cyclic voltammetry. These devices exhibit low switching; voltages and short switching times with reasonable switching stability under atmospheric conditions. (C) 2006 Society of Chemical Industry.
