ABSTRACT:
The invention concerns discrete electrochromic particles comprising conducting, semiconducting or insulating nanoparticles having one or more electrochromic compounds adsorbed on the surface thereof. These particles may be deposited on an electrode in a single process step at a relatively low temperature, thereby allowing the use of heat-sensitive materials such as plastics as flexible substrates for the electrode.
