▎ 摘　　要

NOVELTY - Composite structure comprises a nanofiber substrate having a light-permeable plane net structure, a graphene layer disposed on the surface of the net structure, and an organic compound disposed between the nanofiber substrate and the graphene layer, where the graphene layer includes one or more layers of graphene overlapping to each other and the organic compound has at least a functional group comprising phenyl, pyridyl, pyrimidinyl, carbazolyl, imidazolyl, pyrrolyl, pyrrolidinyl, pyrrolidinone, hydroxyl, carbonyl, amine, secondary amine, tertiary amine and/or fluorine atom. USE - The composite structure is useful for a transparent electrode (claimed), which is useful in information and electronic products such as display panels of mobile phones or tablet personal computers. ADVANTAGE - The composite structure can be simply manufactured with high conductivity, transmittance and flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing the composite comprising (a) inhomogeneously depositing a nanofiber substrate on a transparent substrate to form a light-permeable plane net structure, (b) mixing a graphene oxide and the organic compound and enabling the graphene oxide to be adsorbed on the organic compound to form a first mixture, (c) enabling the organic compound of the first mixture to be adsorbed, by a non-covalent interaction, on the surface of the nanofiber substrate, where the graphene oxide of the first mixture overlaps to each other, and (d) reducing oxygen-containing groups of the graphene oxide to carbon-carbon double bond in the presence of a reducing agent and heat to form the composite.
