Progress in recent years in the field of electrochromic displays based on viologen modified high -surface area nanocrystalline TiO2 film electrodes has moved the technology towards commercialisation. A elec-trochromic device based on a transparent nanostructured TiO2 film modified by organic electrochromphores sup-ported on conducting glass is described. By the chemiabsorption between hydroxyl groups on the surface of nanostructured TiO2 film and phosphonic acid attachment groups which are defivatised on the viologen mole-cules,we obtain a E - paper device with excellent properties of electrochromic. The electrolyte is 0.05mol/L LiCIO4 and0.05mol/L ferrocene in 1,4 -butyrolactone and the counter electrode is conducting glass. It is showed that this electrochromic device is of high stable,its respond time is less millisecond,suggests an elec-trochromic technology with commercial potential in the field of display in the future.
