Abstract
Official abstract text for this publication.
Provided are a functional-group-modified carbon material modified with an isocyanate group or amino group, and a method for producing the material. The material is an isocyanate-group-modified carbon material in which an isocyanate group of a diisocyanate compound is bonded to a graphene-like carbon material, or an amino-group-modified carbon material in which a fragment obtained by radical-decomposing an amino-group-containing azo-type radical initiator is added to the graphene-like carbon material by radical-trapping. The method is a method for producing a functional-group-modified carbon material, including heating and stirring, in a solvent, a graphene-like carbon material, and a diisocyanate compound or an amino-group-containing azo-type radical initiator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A functional-group-modified carbon material, a fragment obtained by radical-decomposing an amino group-containing azo-type radical initiator being added to exfoliated graphite by radical-trapping, wherein the exfoliated graphite is a laminate of plural graphene layers that is obtained by peeling off flakes from non-oxidized ordinary graphite and is a material in which the number of graphene layers laminated is from several to about 200 and the specific surface area is from about 600 to 2500 m 2 /g. 2. A method for producing a functional-group-modified carbon material, comprising: heating and stirring, in a solvent, exfoliated graphite, and an amino-group-containing azo-type radical initiator, wherein the exfoliated graphite is a laminate of plural graphene layers that is obtained by peeling off flakes from non-oxidized ordinary graphite and is a material in which the number of graphene layers laminated is from several to about 200 and the specific surface area is from about 600 to 2500 m 2 /g. 3. The method for producing a functional-group-modified carbon material according to claim 2 , wherein the azo-type radical initiator is an azo-type radical initiator having a secondary or tertiary amino group. 4. A composite material comprising the functional-group-modified carbon material according to claim 1 , and a resin. 5. The composite material according to claim 4 , wherein the resin is in the form of resin fine particles.
