▎ 摘　　要

NOVELTY - A three-dimensional graphene/clay composite aerogel has shape of a hollow rectangular pyramid, hollow triangular pyramid, and hollow cuboid. USE - Three-dimensional graphene/clay composite aerogel used as solar evaporation component in preparation of long-term high-efficiency solar desalination device for water treatment, and organic solvent adsorption (all claimed). ADVANTAGE - The three-dimensional graphene/clay composite aerogel has improved mechanical property and adjustable hydrophilicity and hydrophobicity, and provides device with excellent anti-fatigue performance after being compressed to 90% strain for 20 cycles, which can fully recover to its original height. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the three-dimensional graphene/clay composite aerogel in preparation of long-term high-efficiency solar desalination device.
