Method for producing graphene, method for producing graphene joined body obtained by joining the graphene, and method for producing substrate or part using the graphene or the graphene joined body

摘要

PROBLEM TO BE SOLVED: To provide a method for producing graphene which is an assembly of carbon atoms forming a two-dimensional hexagonal network structure as a large amount of graphene at a low cost.SOLUTION: All interlaminar bonds of graphite crystals forming graphite particles are simultaneously destroyed by application of a load to an assembly of the graphite particles with respect to scaly graphite particles or massive graphite particles which are the most inexpensive graphite single crystal materials, and as a result, a vast number of pieces of graphene are produced.
