Abstract
An electrode is described. The electrode has a substrate having a first and a second surface; a conductive layer; an electroactive layer that includes nanoparticles having an average size from 5 nm to 30 nm; at least one electroactive chemical and at least one organic binder material. The electroactive chemical binds to the surface of the nanoparticles. The conductive layer is disposed on the second surface of the substrate, and the electroactive layer is disposed on the conductive layer. Also described are electrochromic articles including the electrode, and a coating composition that can be utilized to fabricate the electrode.
