▎ 摘  要

NOVELTY - A hydrophobically adjustable graphene/clay composite elastic aerogel comprises graphene aerogel as a matrix, and hydrophilic clay as dispersed phase. USE - Hydrophobically adjustable graphene/clay composite elastic aerogel (claimed). ADVANTAGE - The environmentally-friendly hydrophobically adjustable graphene/clay composite elastic aerogel is economical, and has low density, excellent resilience, hydrophilicity, and hydrophobicity, and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/clay composite elastic aerogel, which involves (i) dispersing hydrophilic clay in deionized water to obtain a clay dispersion, (ii) preparing graphene oxide dispersion by Hummers method or modified Hummers method, (iii) adding clay dispersion to graphene oxide dispersion, and stirring to obtain graphene oxide/clay mixed dispersion, (iv) dissolving reducing agent in graphene oxide/clay mixed dispersion, heating, pre-freezing, thawing, and heating to obtain graphene/clay composite hydrogel, and (v) sequentially dialyzing the graphene/clay composite hydrogel, freeze-drying, and heat treating.
