Methods for producing functionalized graphenes
View Patent ↗Methods for producing functionalized graphene from graphite oxide or graphite are disclosed in which ionic liquids are used as a reaction medium to promote chemical functionalization of the graphene through electrochemically interacted exfoliation of graphene sheets.
1. A functionalized graphene comprising a graphene moiety functionalized with a plurality of silane moieties, and wherein each silane moiety is linked to at least one other silane moiety by a siloxane bond.
2. The functionalized graphene of claim 1 , wherein the graphene moiety further comprises an epoxide group.
3. The functionalized graphene of claim 1 , wherein the silane moiety further comprises an amino group.
4. The functionalized graphene of claim 1 , wherein the silane moiety further comprises a primary amino group.
5. The functionalized graphene of claim 1 , wherein the silane moiety further comprises a hydroxyl group.
6. A composition comprising the functionalized graphene of claim 1 .
7. The functionalized graphene of claim 1 , wherein the silane moiety is selected from (3-aminopropyl)trimethoxysilane, 3-glycidoxypropyldimethoxy-methylsilane, (3-mercaptopropyl)trimethoxysilane, 3-(triethoxysilyl)propylisocyanate, N1-(3-trimethoxysilylpropyl)diethylene-triamine, N-[3-(trimethoxysilyl)propyl]ethylenediamine, (3-aminopropyl)triethoxysilane and any combination thereof.
8. The functionalized graphene of claim 1 , wherein the graphene moiety is covalently linked with the silane moiety through a carboxylate group.
