| titleOfInvention | All-carbon graphene aerogel and preparation method thereof |
| abstract | The invention discloses an all-carbon graphene aerogel and a preparation method thereof. Specifically, adjusting the pH value of a graphene oxide aqueous solution to be alkaline, heating and refluxing, and separating to obtain a black viscous substrate; carrying out acidification treatment and heating reflux on the black viscous substrate, cooling, carrying out centrifugal separation and washing to obtain an aged graphene oxide dispersion liquid; and then uniformly mixing with a polymer aqueous solution, adding glutaraldehyde, heating for crosslinking, placing in a mold, performing directional freezing in liquid nitrogen, thawing at room temperature, adding a chemical reducing agent, heating for reduction, washing with water, drying, and performing high-temperature heat treatment under the protection of an inert atmosphere to finally obtain the all-carbon graphene aerogel. The all-carbon graphene aerogel has the advantages that the interlayer connection is good in the structure, the internal pores are rich, thousands of compression-rebound cycle tests can be borne, and the excellent characteristics of ultralight, super-strong elasticity, high conductivity and the like are shown. |
