Paper Abstract

Electrochromic film has been prepared through liquid phase deposition (LPD) process with an aqueous solution containing an oxalatotungstate (V) complex, and its chemical and electrochromic properties have been investigated. Results showed that two redox couples exist on a cyclic voltammogram and that oxalate ligands would be present in the film coordinating to the tungsten atoms. The redox couple at positive potential is considered due to movement of the cation getting into and out of the sites like crown ether formed by oxlato ligands. The film has fairly good electrochromism exhibiting reversibility as much as 105colourbleach cycles or more in response to an applied potential.
