▎ 摘  要

NOVELTY - Preparation of graphene oxide (GO)/hydroxyapatite (HAP) nanowire multifunctional adsorption aerogel comprises mixing GO aqueous dispersion, HAP nanowire aqueous dispersion and chemical reducing agent by stirring, ultrasonically processing to disperse uniformly, conducting mild chemical reduction-freezing and thawing-deep reduction to obtain reduced (r)GO/HAP self-assembly, sequentially freeze drying to obtain rGO/HAP aerogel, and carrying out high temperature carbonization treatment or surface hydrophilic modification. USE - The method is for preparation of GO/HAP nanowire multifunctional adsorption aerogel (claimed). ADVANTAGE - The method is simple and fast, has mild reaction condition, and provides aerogel, which achieves efficient adsorption of different organic solvents/oil phases or fluoride ions, excellent physical and chemical properties and mechanical properties, and high adsorption capacity, and can be used repeatedly for multiple times. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for GO/HAP nanowire multifunctional adsorption aerogel.
