▎ 摘　　要

NOVELTY - A graphene oxide structure (10) has a ratio (R2) of the peak area (P2c) obtained by adding the peak area of a peak derived from a bond between carbon and hydrogen and the peak area of a peak derived from a bond between carbon and carbon, with respect to the peak area (P2o) of a peak derived from a bond of carbon and oxygen among the spectra of C1s on the other surface of the graphene oxide structure, of less than 1. The ratio (R1) of the peak area (P1c) obtained by adding the peak area of a peak derived from a bond between carbon and hydrogen and the peak area of a peak derived from a bond between carbon and carbon among the spectra of C1s on one surface of the graphene oxide structure measured by X-ray photoelectron spectroscopy with respect to the peak area (P1o) of a peak derived from a bond between carbon and oxygen, with respect to the ratio (R2) is more than 3. USE - Graphene oxide structure is used for electronic apparatus and machinery. ADVANTAGE - The lightweight graphene oxide structure has excellent thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene oxide structure, which involves forming the graphene oxide film on an electrode, energizing an electrode on which the graphene oxide film is formed as a cathode arranged together with an anode in an electrolytic solution, reducing the side of the graphene oxide film in contact with the electrode, and forming the graphene oxide layer on the surface of the substrate. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of graphene oxide structure. Reduced graphene oxide (1) Graphene oxide (2) Graphene oxide structure (10)
