With a total of 4 patents, his work showcases innovative methods and compositions that enhance the functionality and aesthetics of various substrates.

Latest Patents

One of his latest patents is titled "Compositions and methods for forming coatings of selected color on a substrate and articles produced thereby." This invention involves applying a copper-containing component and a manganese-containing component onto a substrate's surface to create a coating with a specific color ratio. For instance, a brown color is achieved with a film molar ratio of copper to manganese above 1, while an amber color requires a ratio below 1, and a blue color is achieved with a ratio of about 1. Additionally, this patent addresses the issue of color shifting in multi-component coatings by introducing a concentration gradient layer of an oxide of the most mobile species in the coating.

Another significant patent is "Fabrication of electrochromic device with plastic substrates." This invention describes a method for creating an electrochromic device using organic polymer substrates. Each substrate is coated with an organic polymer primer, followed by the deposition of an electroconductive metal oxide film. Electrochromic materials are then applied to the conductive films, and the substrates are aligned with these materials facing each other. A preformed sheet of an ion-conducting polymer is placed between the electrochromic layers, and the assembly is autoclaved to create a functional device.
