Publication number: 20140030636Abstract: In general, in one aspect, a graphene film is used as a protective layer for current collectors in electrochemical energy conversion and storage devices. The graphene film inhibits passivation or corrosion of the underlying metals of the current collectors without adding additional weight or volume to the devices. The graphene film is highly conductive so the coated current collectors maintain conductivity as high as that of underlying metals. The protective nature of the graphene film enables less corrosion resistant, less costly and/or lighter weight metals to be utilized as current collectors. The graphene film may be formed directly on Cu or Ni current collectors using chemical vapor deposition (CVD) or may be transferred to other types of current collectors after formation. The graphene film coated current collectors may be utilized in batteries, super capacitors, dye-sensitized solar cells, and fuel and electrolytic cells.Type: ApplicationFiled: July 26, 2012Publication date: January 30, 2014Applicant: Bluestone Global TechInventors: Xin Zhao, Yu-Ming Lin

Publication number: 20130256011Abstract: Disclosed herein is a method of fabricating a transparent conductive film, including preparing a carbon nanotube composite composition by blending a carbon nanotube in a solvent; coating the carbon nanotube composite composition on a base substrate to form a carbon nanotube composite film, and acid-treating the carbon nanotube composite film by dipping the carbon nanotube composite film in an acid solution, followed by washing the carbon nanotube composite film with distilled water and drying the washed carbon nanotube composite film to form a transparent electrode on the base substrate. The transparent conductive film can have excellent conductivity, transparency and bending properties following acid treatment, so that it can be used in touch screens and transparent electrodes of foldable flat panel displays. Further, the carbon nanotube composite conductive film can have improved conductivity while maintaining transparency after acid treatment.Type: ApplicationFiled: May 31, 2013Publication date: October 3, 2013Inventors: Young Kyu CHANG, Seung Yong BAE, Young Sil LEE, Young Hee LEE, Hong Zhang GENG

Publication number: 20130260136Abstract: Disclosed herein are solvent free, dry coating processes for applying a layered material such as graphene, nanoplate graphite, etc., to a substrate. The applied layered material is devoid of any dispersant and substantially uniform in thickness. Generally, a layered material precursor composition is mixed with a milling medium so that the milling medium is coated with the layered material. The substrate is then contacted with the coated milling medium. The layered material on the milling medium transfers to the substrate to form a coating on the substrate. Such processes may be especially useful for applying conductive films onto a polymeric substrate without the need for additives such as a surfactant or a polymeric binder.Type: ApplicationFiled: April 3, 2012Publication date: October 3, 2013Applicant: Xerox CorporationInventors: Yiliang Wu, Sandra J.
