▎ 摘　　要

NOVELTY - Graphene oxide composition comprises sheets of graphene oxide crosslinked with one another via metal cations in an oxidation state of at least 3+. USE - The graphene oxide composition is useful in a composite composition (claimed). ADVANTAGE - The graphene oxide composition utilizes the sheets of crosslinked graphene oxide which are: stable under ambient atmospheric conditions; and inflammable under ambient atmospheric conditions upon exposure to an open flame (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a composite composition comprising a substrate, and a graphene oxide film positioned over the substrate, where the graphene oxide film comprises sheets of graphene oxide crosslinked with one another via metal cations in the oxidation state of at least 3+; and (2) making the graphene oxide composition, comprising providing a mixture of graphene oxide sheets and metal cations in polar continuous phase, and crosslinking the graphene oxide sheets with the metal cations.
