▎ 摘　　要

NOVELTY - Preparation of carbon nanotube-modified graphene aerogel comprises dispersing amine-functionalized carbon nanotube, surfactant, graphene oxide, and reducing agent in water to formhomogeneous mixed dispersion; stirring and foaming mixed dispersion to obtain mixed foaming liquid; reacting mixed foam liquid at 60-100 degrees C for 2-12 hours; cooling at 15-35 degrees C to obtain carbon nanotube-modified graphene hydrogel; and subjecting carbon nanotube-modified graphene hydrogel to freeze-treatment at - 10 degrees C to - 60 degrees C and to atmospheric pressure drying treatment to obtain carbon nanotube-modified graphene aerogel. USE - The method is for preparation of carbon nanotube-modified graphene aerogel used for oil-water separation (claimed). ADVANTAGE - The method produces carbon nanotube-modified graphene aerogel with good elasticity, mechanical properties and hydrophobic properties.
