▎ 摘  要

NOVELTY - Strengthening the interaction between graphene layer comprises changing the coupling force between graphene layers by applying pressure to the graphene through an anvil press. USE - The method is useful for strengthening the interaction between graphene layer. ADVANTAGE - The method: enables high-intensity coupling between graphene layers; and is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for detecting the interaction between graphene layers comprising placing the counter-anvil press installed with the graphene to be detected on the sample stage of the pump-probe ultrafast time-domain spectroscopy system, adjusting pump light power and probe light power, measuring the Raman fluorescence peak calibration pressure of the pressure calibration object by Raman spectroscopy, switching to the pump-probing ultra-fast time-domain spectroscopy system to measure the relaxation time, adjusting the anvil press to change the pressure between graphene layers, and judging the interaction between graphene layers according to different relaxation times under different pressures.
