Abstract

Electroconductive particles comprising an electrically conductive non-metallic particle coated with an electrochromic material. Such electroconductive particles can be provided in polymeric dispersions that are useful for preparing electrically conductive, essentially ionically isolative composite layers. Composite layers (3a) can be used in laminates for electrochromic displays where an ionically conductive layer (4) is in contact with electrochromic material. By applying an electrical potential across the interface of the ionically conductive layer and the electrochromic material, an electrochromic effect can be generated. A preferred electroconductive particle comprises titanium dioxide particles coated with a layer of antimony-doped tin oxide and a layer of electrochromic material such as polyaniline or polypyrrole. In preferred dispersions and laminates the electroconductive particle is dispersed in a light transmitting polymer matrix. The materials of this invention allow for the high speed fabrication of flexible displays, e.g. by printing methods.
