▎ 摘　　要

NOVELTY - Preparing graphene microchip involves adding a blasting agent into graphite and peeling the blasting graphite to obtain a graphene microchip. The blasting agent is a substance capable of generating a solid, a gas or a liquid in a short time and generating an impact force or a substance capable of volumizing itself in a short time. USE - Method for preparing graphene microchip (claimed). ADVANTAGE - The method enables to prepare graphene microchip, which has convenient operation, fast processing and excellent industrialized prospect.
