Nanostructured Electrochromic Layers

Abstract

We have proposed a new method to obtain the electrochromic materials by electrochemical polymerization of aminoarene monomer inside a TiO₂ nanocrystalline layer on the ITO surface. It has been found that a conducting polymer integrated into the nanoporous titanium dioxide matrix causes a significant improvement in electrochemical and electrooptical properties of the hybrid layer and provides a higher contrast ratio in comparison with that for a polyaminoarene layer on the free ITO surface, as well as the widening of the angle of view for the known non-emissive display.
