US Patent 7270880 - Electrochromic nanoparticles


Electrochromatic materials have the property of changing color based on an applied electrical potential and can be used in a variety of applications including displays and smart glass that can change shading properties. This patent from NTERA Ltd. presents some basic claims to the use of nanoparticles with electrochromatic compounds adsorbed on the surface. Claim 1 reads:

1. Discrete electrochromic particles comprising conducting, semiconducting or insulating nanoparticles, said nanoparticles having an average particle size of up to 80 nm and one or more electrochromic compounds adsorbed on the surface thereof.
