▎ 摘　　要

NOVELTY - Method for ultra-fast growth of graphene, comprises (i) subjecting the substrate material to carbonization treatment to form a carbon layer or a metal carbon layer on the surface; and (ii) quenching the carbonized substrate material by heating the substrate material to 500-2000 degrees C for 1 mu second to 10 seconds, and then immediately cooling. USE - The method is useful for ultra-fast growth of grapheme. ADVANTAGE - The method achieves graphene functionalization on the surface of the target material and simultaneously has the characteristics of wide range of adaptation to materials (type, size) and environment (vacuum, inert atmosphere or atmosphere), fast speed, and low energy consumption; utilizes pulse current, eddy currents excited by electromagnetic induction, and microwave alternating electromagnetic fields to directly heat the substrate, and completes the growth of graphene on the surface of the substrate in a very short time and has good interfacial contact; ensures that a large area of graphene is generated on the surface of the substrate while avoiding damages e.g. melting and oxidation to the substrate caused by high temperature, and expands the types of graphene functionalized substrate materials, and the size of the substrate is not limited by the size of the tube furnace, can be used for rapid graphene functionalization of large-size substrate materials; simultaneously can effectively speed up production and reduce energy consumption and costs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene product prepared by above method.
