    摘要： A three-dimensional graphene structure, and methods of manufacturing and transferring the same including forming at least one layer of graphene having a periodically repeated three-dimensional shape. The three-dimensional graphene structure is formed by forming a pattern having a three-dimensional shape on a surface of a substrate, and forming the three-dimensional graphene structure having the three-dimensional shape of the pattern by growing graphene on the substrate on which the pattern is formed. The three-dimensional graphene structure is transferred by injecting a gas between the three-dimensional graphene structure and the substrate, separating the three-dimensional graphene structure from the substrate by bonding the three-dimensional graphene structure to an adhesive support, combining the three-dimensional graphene structure with an insulating substrate, and removing the adhesive support.

    摘要： Disclosed herein are a dispersed solution of carbon nanotubes including carbon nanotubes, an organic solvent, a spacer, and a dispersant, and a method of preparing the same. The dispersed solution of the carbon nanotubes includes both the spacer, which reduces the van der Waals force of the carbon nanotubes and prevents bundling of the carbon nanotubes, and the dispersant, which maintains the debundling and stability of the carbon nanotubes, thereby improving the dispersibility of the carbon nanotubes. The method of preparing the dispersed solution of the carbon nanotubes can easily produce a dispersed solution of carbon nanotubes without performing a separate chemical treatment.

    摘要： Provided is a carbon nanofiber, wherein the carbon nanofiber has a surface oxygen content of at least 0.03 calculated by the formula: Oxygen content=[atomic percentage of oxygen/atomic percentage of carbon] using atomic percentages of oxygen and carbon, respectively calculated from an area of an oxygen peak having a binding energy of 524 to 540 eV, an area of a nitrogen peak having a binding energy of 392 to 404 eV, and an area of a carbon peak having a binding energy of 282 to 290 eV in X-ray photoelectron spectroscopy. The nanofibers have high surface oxygen content and may have metal catalyst nano particles densely and uniformly distributed on the outer wall of the carbon nanofibers, thereby having high electrochemical efficiency.
