NOVELTY - Preparing laser-induced coated graphene material comprises choosing and determining carbon-containing precursor materials and coating substrate material, coating the target coating substrate material by the carbon-containing precursor material, and reducing and converting the carbon-containing precursor material on the surface into graphene by using laser induction to obtain the corresponding laser-induced coated graphene material. USE - The method is useful for preparing laser-induced coated graphene material, which is useful for optimizing and modifying plastics, rubber, coating raw materials, and soil, garbage, water quality improvement and purification treatment (claimed), and in important fields i.e. petroleum, chemical industry, metallurgy, energy, environmental protection, construction, and machinery. ADVANTAGE - The method: is economical; has simple coating process, coating effect and excellent performance characteristics; realizes the graphene coating and complexing of various types of materials; and significantly enhances the comprehensive properties of the substrate material.
