▎ 摘　　要

NOVELTY - The method involves providing a substrate. A hydrophilic layer is formed on the substrate. A graphene oxide layer is formed on the hydrophilic layer. A portion of the graphene oxide layer is reduced into reduced graphene oxide by a laser to form a pattern of the reduced graphene oxide on the graphene oxide layer (304). The hydrophilic layer is formed by applying piranha solution to react with a surface of the substrate. The graphene oxide solution is spin-coated on the hydrophilic layer (303). The graphene oxide solution is dried on the hydrophilic layer. USE - Method for fabricating a reduced-graphene oxide circuit. ADVANTAGE - The method enables fabricating a reduced-graphene oxide circuit with a quick prototype process, high throughput, environmentally friendly, high yields, high resolution and precision. The method enables realizing high hydrophobicity of graphene in conjunction with surface roughness with a suitable dimension to achieve high optical transparency and conductivity. The method enables repelling water or moisture to attain self-cleaning ability in an easy manner. The method enables increasing conductivity due to reduction of the graphene when spin speed is increased, thus reducing film thickness.
