▎ 摘　　要

NOVELTY - A graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite aerogel comprises a graphene three-dimensional framework, a black phosphorus nanosheet, and a sulfur-containing ionic liquid supported on graphene three-dimensional framework. The black phosphorus nanosheet is surrounded by the sulfur-containing ionic liquid. The graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite aerogel has a three-dimensional porous network structure. USE - Graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite aerogel (claimed). ADVANTAGE - The graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite aerogel has high elasticity, recoverability, conductivity and stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite aerogel, which involves: (1) mixing solution containing black phosphorus nanosheet and sulfur-containing ionic liquid and graphene oxide aqueous solution, and uniformly mixing and stirring with reducing agent to obtain mixed solution; (2) carrying out heating on mixed solution under water bath and oxygen-free condition at 75-100 degrees C, and reacting for 1-3 hours to obtain graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite wet gel; and (3) sequentially placing graphene/black phosphorus nanosheet/sulfur-containing ionic liquid composite wet gel in a hydrophilic organic solvent and water for purification, and then carrying out freeze-drying to obtain product.
