Abstract
Official abstract text for this publication.
Graphene aerogels with high conductivity and surface areas including a method for making a graphene aerogel, including the following steps: (1) preparing a reaction mixture comprising a graphene oxide suspension and at least one catalyst; (2) curing the reaction mixture to produce a wet gel; (3) drying the wet gel to produce a dry gel; and (4) pyrolyzing the dry gel to produce a graphene aerogel. Applications include electrical energy storage including batteries and supercapacitors.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising at least one graphene aerogel comprising a three-dimensional structure of graphene sheets, wherein the graphene sheets are directly chemically crosslinked with each other by covalent carbon bonds. 2. The composition of claim 1 , wherein the atomic oxygen content is 5% or less. 3. The composition of claim 1 , wherein the graphene sheets are randomly oriented. 4. The composit…
