▎ 摘　　要

NOVELTY - Fabricating graphene table tennis bat three-ply substrate comprises providing graphene oxide, reacting the graphene oxide with a base at room temperature, subjecting to a nucleophilic substitution reaction with a sulfonic acid group-rich acid and/or a sulfonic acid group-rich acid derivative, adding a nano-scale polar particle filler, and finally mixing with a thickener to prepare a composite graphene oxide solution, applying the composite graphene oxide solution to the surface of the first substrate to form a graphene oxide film layer on the surface of the substrate, and covering the surface of the graphene oxide film layer with at least a second substrate. USE - The substrate is useful for graphene table tennis bat. ADVANTAGE - The substrate good elasticity and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene table tennis bat, comprising graphene table tennis bat three-ply board substrate.
