▎ 摘  要

NOVELTY - A graphene-carbon nanotube composite total carbon ultralight elastic aerogel comprises carbon nanotube absorbed on the surface of graphene having macroporous structure. The composite has density of 0.5-350 mg/cm3, aperture of 50 nm-500 microns, compressibility of 30-80%, excellent elasticity at 196-1000 degrees C and conductivity of more than 100 S/cm. USE - Graphene-carbon nanotube composite total carbon ultralight elastic aerogel. ADVANTAGE - The graphene-carbon nanotube composite total carbon ultralight elastic aerogel is manufactured by a simple and environmentally-friendly process. The aerogel has low density, high conductivity, large specific surface area and wide elastic temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the graphene-carbon nanotube composite total carbon ultralight elastic aerogel, which involves dispersing (in parts weight) graphene oxide (1) into water (10-4000) to form graphene oxide dispersion, dispersing carbon nanotube (1) into graphene oxide dispersion (5-4000) to obtain graphene oxide-carbon nanotube dispersion, freeze-drying or supercritically drying the dispersion to obtain graphene oxide-carbon nanotube (CNT) composite aerogel, reducing the aerogel by chemical reducing method or high temperature thermal recovery method to obtain the ultralight elastic aerogel.
