RAYFORD H. BULLOCH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10882949
    Abstract: Conjugated copolymers are provided that can be processed in a variety of solvents and can be rendered solvent-resistant when needed. The copolymers can be solution cast from nonpolar, polar, and aqueous solvents. After casting a polymer layer, the polymer can be rendered solvent resistant, thereby providing for improved stability and multi-layer processing and in electrochromic devices where the polymer layer is in contact with a nonpolar or polar solvent or electrolyte. Methods of making the copolymers are also provided, as well as methods of solution casting the polymers from a variety of nonpolar organic, polar, and aqueous solvents. Electrochromic devices are demonstrated having electrode(s) containing these polymers, including a variety of supercapacitor devices capable of using organic, biological, and aqueous electrolytes. Some of these electrodes demonstrate superfast switching and large power densities, showing promise for applications in supercapacitor batteries.
