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.
一种联合生产-功能化工艺,用于从预插层、氧化或卤素化石墨材料生产化学功能化纳米石墨材料,包括:(A)从预插层、氧化或卤素化石墨材料中生产剥离的石墨,其中石墨材料选自天然石墨、人造石墨、高度定向热解石墨、碳纤维、石墨纤维、碳纳米纤维、石墨纳米纤维、介孔碳微球、石墨化焦和其组合;(B)在液体介质中分散剥离的石墨和叠氮化合物或双自由基化合物,形成悬浊液;(C)将悬浊液暴露于所需强度的超声波下超声处理一段足够的时间,以产生纳米石墨片并使纳米石墨片与叠氮化合物或双自由基化合物发生化学反应,以生产功能化的纳米石墨材料。
