摘要: Disclosed are a graphene composite nanofiber and a preparation method thereof. The graphene composite nanofiber is produced by dispersing graphenes to at least one of a surface and inside of a polymer nanofiber or a carbon nanofiber having a diameter of 1˜1000 nm, and the graphenes include at least one type of monolayer graphenes, and multilayer graphenes having a thickness of 10 nm or less. The graphene composite nanofiber can be applied to various industrial fields, e.g., a light emitting display, a micro resonator, a transistor, a sensor, a transparent electrode, a fuel cell, a solar cell, a secondary cell, and a composite material, owing to a unique structure and property of graphene.

摘要: The present invention relates to a nitrogen-doped 3-D porous graphene assembly and a method of preparing the same. The present invention provides a method of preparing a nitrogen-doped graphene assembly, the method including the steps of mixing a graphene oxide solution with a melamine solution, freezing the mixed solution of graphene oxide and melamine, drying the frozen solution in a frozen state to prepare a graphene assembly, and heating the graphene assembly at a predetermined temperature under the argon atmosphere for a predetermined to time, in which a mass ratio of the graphene oxide and the melamine in the mixed solution is 19:1 to 4:1. According to the present invention, a uniformly nitrogen-doped 3-D porous graphene assembly may be synthesized.
