Abstract
Official abstract text for this publication.
Providing a modified-graphene-like carbon material into which hydroxyl groups are introduced. By reacting a graphene-like carbon material with hydrogen peroxide, a hydroxyl group is introduced into the graphene-like carbon material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A modified-graphene-like carbon material, wherein an amount of a hydroxyl group as measured by a quantitative method using 2,2′-diphenyl-1-picrylhydrazyl is 0.3 mmol/g to 10.0 mmol/g, and wherein an amount of a carboxyl group as measured by a quantitative method using NaHCO 3 is 1.0 mmol/g or less. 2. A resin composite material obtained by dispersing the modified-graphene-like carbon material according to claim 1 in a resin. 3. A modified-graphene-like carbon material obtained by a method comprising reacting a graphene-like carbon material with hydrogen peroxide to introduce a hydroxyl group into the graphene-like carbon material, wherein an amount of the hydroxyl group in the modified-graphene-like carbon material as measured by a quantitative method using 2,2′-diphenyl-1-picrylhydrazyl is 0.3 mmol/g to 10.0 mmol/g, and wherein an amount of a carboxyl group as measured by a quantitative method using NaHCO 3 is 1.0 mmol/g or less. 4. A resin composite material obtained by dispersing the modified-graphene-like carbon material according to claim 3 in a resin. 5. A modified-graphene-like carbon material obtained by a method comprising reacting a graphene-like carbon material with hydrogen peroxide to introduce a hydroxyl group into the graphene-like carbon material, wherein the introduction of the hydroxyl group into the graphene-like carbon material is performed in the presence of an iron catalyst, wherein an amount of the hydroxyl group in the modified-graphene-like carbon material as measured by a quantitative method using 2,2′-diphenyl-1-picrylhydrazyl is 0.3 mmol/g to 10.0 mmol/g, and wherein an amount of a carboxyl group as measured by a quantitative method using NaHCO 3 is 1.0 mmol/g or less. 6. A method for producing the modified-graphene-like carbon material according to claim 3 , comprising reacting a graphene-like carbon material with hydrogen peroxide to introduce a hydroxyl group into the graphene-like carbon material. 7. The method for producing the modified-graphene-like carbon material according to claim 6 , wherein the introduction of the hydroxyl group into the graphene-like carbon material is performed in the presence of an iron catalyst.
