▎ 摘　　要

NOVELTY - Preparing graphene compressible aerogels based on hydrothermal reduction method comprises carrying out oxidation of graphene, to obtain graphene oxide as raw material, taking ~g-oxo-1-pyrene butyric acid (OPBA) as binder, preparing reduced graphene oxide-~g-oxo-1-pyrene butyric acid (RGO-OPBA) airgel by hydrothermal reduction, coating RGO-OPBA aerogel on HMP (high molecular weight polymer solution), removing solvent, to obtain RGO-OPBA-HMP aerogel. USE - The method is useful for preparing graphene compressible aerogels based on hydrothermal reduction method (claimed). ADVANTAGE - The method produce product having high-elastic state of graphene oxide aerogel, and simple preparation procedure; and is environmentally friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) reduced graphene oxide-~g-oxo-1-pyrene butyric acid-high molecular weight polymer solution aerogel obtained by above mentioned method; and (2) aerogel with density of 1-22.54 mg/cm3.
