▎ 摘　　要

NOVELTY - Simultaneous characterization of mechanical properties of graphene based on graphene-based folding comprises e.g. respectively making two same poly(methyl methacrylate) (PMMA)/graphene composite films by dry graphene transfer technique, wet transfer techniques, electrochemical transfer technology, directly transferring technology or Roll to Roll transfer technology, the graphene in the composite film are placed on the test substrate and the target substrate, after cooling treatment under the same condition is different from the thermal expansion coefficient of the target and testing substrate. USE - The method is useful for simultaneous characterization of mechanical properties of graphene based on graphene-based folding. ADVANTAGE - The method can process synchronous with the graphene to quickly simply represent the elastic modulus of graphene, the surface stress and the layer and other mechanical characteristics. DETAILED DESCRIPTION - Simultaneous characterization of mechanical properties of graphene based on graphene-based folding comprises respectively making two same poly(methyl methacrylate) (PMMA)/graphene composite films by dry graphene transfer technique, wet transfer techniques, electrochemical transfer technology, directly transferring technology or Roll to Roll transfer technology, the graphene in the composite film are placed on the test substrate and the target substrate, after cooling treatment under the same condition is different from the thermal expansion coefficient of the target substrate and graphene-based on the testing substrate, matching to generate stress caused by folds, finally graphene can be evaluated by measuring the wavelength and amplitude of the graphene wrinkles graphene mechanical property, the evaluation, the specific measurement wavelength and amplitude in the fold of the following formula to solve elastic modulus of graphene and graphene thickness physical parameter experiment by SEM using the formula as given in the specification.
