▎ 摘　　要

NOVELTY - Electrodes spaced apart from each other are formed on substrate, supporting patterns are formed (S20) on the electrodes, patterns are coated with graphene-oxide-containing solution to form (S30) composite pattern. The coated supporting pattern is separated (S40) from composite pattern, to obtain graphene electronic device. USE - Fabrication of electronic device. Uses include but are not limited to display, lithium-ion cell, capacitor electrode and filter. ADVANTAGE - The method enables efficient fabrication of graphene electronic device, by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart of fabrication of graphene electronic device. Providing substrate (S10) Formation of support patterns (S20) Formation of composite patterns (S30) Separating coated supporting pattern from composite pattern (S40)
