Production process for chemically functionalized nano graphene materials |
摘要 |
A combined production-functionalization process for producing a chemically functionalized nano graphene material from a pre-intercalated, oxidized, or halogenated graphite material, comprising: (A) Producing exfoliated graphite from the pre-intercalated, oxidized, or halogenated graphite material, wherein the graphite material is selected from the group consisting of natural graphite, artificial graphite, highly oriented pyrolytic graphite, carbon fiber, graphite fiber, carbon nano-fiber, graphitic nano-fiber, meso-carbon micro-bead, graphitized coke, and combinations thereof; (B) Dispersing the exfoliated graphite and an azide or bi-radical compound in a liquid medium to form a suspension; (C) Subjecting the suspension to ultrasonication with ultrasonic waves of a desired intensity for a length of time sufficient to produce nano graphene platelets and to enable a chemical reaction to occur between the nano graphene platelets and the azide or bi-radical compound to produce the functionalized nano graphene material. |

1. A combined production-functionalization process for producing a chemically functionalized nano graphene material from a halogenated graphite material and an azide or bi-radical compound, comprising:
(A) Producing exfoliated halogenated graphite from said halogenated graphite material, wherein said graphite material is selected from the group consisting of carbon fiber, graphite fiber, carbon nano-fiber, graphitic nano-fiber, meso-carbon micro-bead, graphitized coke, and combinations thereof; (B) Dispersing said exfoliated halogenated graphite and said azide or bi-radical compound in a liquid medium to form a suspension; and (C) Subjecting said suspension to ultrasonication with ultrasonic waves of a desired intensity for a length of time sufficient to produce nano graphene platelets and to enable a chemical reaction to occur between said nano graphene platelets and said azide or bi-radical compound to produce said functionalized nano graphene material. |
