U.S. Patent number 7,585,349 has been assigned to the University of Washington, covering an invention by Younan Xia and Yougang Sun, which has been licensed exclusively to Cambrios in its specific field of use.
Cambrios has developed a material that the company sells under the trademark ClearOhm. In one form, this material is composed of silver nanowires distributed on surfaces to create transparent conductive networks. The nanocoating material shows promise as an alternative to ITO and other transparent conductive oxides.
Cambrios is selling ClearOhm coating materials and ClearOhm material coated on substrates such as polyethylene terephthalate (PET) film, glass, polycarbonate and other substrates relevant to electronics, displays, touch screens, thin-film photovoltaic cells, organic LED (OLED) devices, e-paper, and others.
“There are only a few ways to synthesize highly crystalline, highly conductive silver nanowires,” said Dr. Michael Knapp, president and CEO of Cambrios. “The University of Washington’s patent covers an extremely important method for this purpose because it is scaleable and cost-effective. At Cambrios, we have spent considerable time and resources developing a process that produces very pure, high performance materials that are now being commercialized. We congratulate Drs. Xia and Sun for the patent award.”
