▎ 摘　　要

NOVELTY - Three-dimensional printing preparation of high crystalline quality of graphene macrobody comprises firstly synthesizing the polymer microporous membrane, laying the polymer microporous membrane on the substrate, using high-energy beams to bombard polymer microporous films to form graphene crystal films on substrates, repeating the operations of tiling the polymer microporous film and bombarding the polymer microporous film with high-energy beams many times to realize the three-dimensional printing preparation of graphene macroscopic body. USE - Three-dimensional printing preparation of high crystalline quality of graphene macrobody used in electrochemical energy storage, sensor, thermal control, catalysis and micro-nano electronic device. ADVANTAGE - The method provides high crystal quality of the graphene macroscopic body, and provides graphene with thickness of centimeter level, can realize the graphene adjustment of the thickness, providing an effective method for the actual large quality or large volume application graphene of the nanometre material.
