▎ 摘　　要

NOVELTY - Graphene film surface hydrophilicity improvement involves configuring surfactant solution, and then placing graphene film with substrate in the surfactant solution for a period of time. USE - Method for improving surface hydrophilicity of graphene film (claimed). ADVANTAGE - The method improves surface hydrophilicity of the graphene film in a simple, cost-effective and eco-friendly manner by saving labor costs and material costs. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the hydrophobicity of the graphene membrane transferred onto the silicon/silicon dioxide substrate before and after the treatment of the surfactant.
