Abstract: Provided herein are high performance direct deposit electrodes that do not require the use of a binder, as well as processes of manufacturing the same by an electrospray process.

Abstract: Disclosed is a functionalized graphene containing two or more amines having excellent electrical, thermal and mechanical properties by allowing good interfacial bonding force and uniform dispersion with a thermoplastic polymer, and a method for preparing the functional graphene. The functionalized graphene comprises a carbon material selected from the group consisting of graphene, reduced graphene, graphene oxide, and mixture thereof; and a monovalent amine group and a bivalent or higher amine group which are bonded to the carbon material.

Abstract: The present invention relates to a carbon-metal composite and a method for preparing carbon-metal composite, and more particularly to a method for preparing carbon-metal composite, which: is capable of reducing graphene oxide; which is capable of decreasing the steps and the time for hybridization of graphene which is obtained from the reduction, graphene or carbon nanotube, with metal; which is done under mild condition and; also which is capable of lowering resistivity of the carbon-metal composite. The method for preparing the carbon-metal composite comprises the steps of: reacting a composition containing a carbon compound selected from a group consisting of graphene, graphene oxide and carbon nanotube, a metallic precursor, a reducing agent and a solvent; and removing solvent partially or wholly from the composition reaction-completed.
