NOVELTY - Hydrophilic modification of surface comprises irradiating ions of high energy inert gas to the surface of the carbon-based material. USE - The method is useful for hydrophilically modifying carbon-based material surface (claimed). ADVANTAGE - The method modifies the surface of the carbon-based material to exhibit hydrophilic properties, is environment friendly and is simple in process without deformation of the base material, controls the reaction by adjusting the ion irradiation amount or energy and maintains excellent material properties.
