▎ 摘  要

NOVELTY - Predicting graphene separation condition, comprises either: by using required load (a) stabilizing graphene laminate on solvent, (b) applying required load to uppermost graphene monolayer of graphene laminate to generate a predetermined displacement, (c) calculating potential energy required for separating by the predetermined displacement, (d) repeatedly generating the predetermined displacement to completely peel the uppermost graphene monolayer from graphene laminate, and (e) calculating an integral value up to a complete peeling point based on the required load to calculate total required energy for complete peeling; or by using interlayer insert (a1) stabilizing graphene laminate on solvent, (b1) inserting at least one interlayer inserting material between uppermost graphene monolayer of the graphene laminate for predetermined time at predetermined rate, (c1) completely peeling the uppermost graphene monolayer from the graphene laminate, and (d1) calculating required output. USE - The method is useful for predicting graphene separation condition. ADVANTAGE - The method prevents trial and error or loss which cannot be predicted in peeling of the graphene in advance, and can easily predict physical conditions e.g. temperature. DETAILED DESCRIPTION - Predicting graphene separation condition, comprises either: by using required load (a) stabilizing graphene laminate on a solvent, (b) applying a required load to the uppermost graphene monolayer of the graphene laminate to generate a predetermined displacement, (c) calculating potential energy required in the step of separating by the predetermined displacement, (d) repeating the step of generating the predetermined displacement to completely peel the uppermost graphene monolayer from the graphene laminate, and (e) calculating an integral value up to a complete peeling point based on the required load to calculate total required energy for complete peeling, where the required load is calculated by using equation-1 as given in specification; or by using interlayer insert (a1) stabilizing graphene laminate on solvent, (b1) inserting at least one interlayer inserting material between uppermost graphene monolayer of the graphene laminate for predetermined time at predetermined rate, (c1) completely peeling the uppermost graphene monolayer from the graphene laminate, and (d1) calculating a required output through equation-2 as given in specification.
