▎ 摘　　要

NOVELTY - Locally reducing graphene oxide, comprises (a) preparing a graphene oxide thin film (100), (b) forming a self-reactive layer on upper surface of the graphene oxide thin film, (c) locally reducing a portion of the graphene oxide thin film in which the self thin film layer is formed by applying magnetic field, and (d) removing the self-reactive layer to obtain locally reduced graphene oxide thin film (110). USE - The graphene oxide is useful for electronic devices, transparent display material, semiconductor material and transparent electrode material. ADVANTAGE - The graphene oxide has electrical conductivity and processability, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide thin film comprising a locally reduced portion. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the locally reduced graphene oxide. Graphene oxide thin film (100) Locally reduced graphene oxide thin film (110)
