▎ 摘　　要

NOVELTY - The method involves preparing and cleaning an insulation substrate. The insulation substrate is subjected to a drying process. A graphene thin film layer is prepared on the insulation substrate. An outer edge of the graphene thin film layer is coated using a hydrophobic material. USE - Graphene-liquid energy conversion method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating a graphene-liquid energy conversion method.
