▎ 摘 要
NOVELTY - Preparation of graphene superelastic composite having layered structure, involves dissolving a water-soluble polymer in water to obtain 5-50 mg/mL polymer solution, adding graphene oxide nanosheets to the polymer solution, ultrasonically blending to obtain 15 mg/mL graphene oxide nanosheet mixed solution, freezing in a freezing mold, vacuum-freeze-drying for 24-48 hours to obtain a macroscopic graphene layered structure assembly, and reducing under inert gas or reducing gas protection at 600-1000 degrees C for 1-4 hours. USE - Preparation of graphene superelastic composite having layered structure, for use as sensitive material in pressure sensors (claimed). ADVANTAGE - The method provides graphene superelastic composite having excellent dynamic resilience, fatigue resistance, and micro-pressure induction characteristics.
