▎ 摘  要

NOVELTY - Composition comprises unaffixed graphene particulates, where at least 90% of the graphene particulates have widths within plus minus 3 nm from the mean width of the graphene particulates. USE - The composition is useful in variety of electrical applications such as high speed transistors, electronic devices, sensors (biological, physical and explosive), solar cells, optoelectronic devices, logic devices, ultra capacitors, actuators, coulomb blockade device, ultra-strong paper, field emission devices, transparent electrodes, conductive pastes and optical/fluorescent devices. ADVANTAGE - The composition is in relatively pristine condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing graphene particulates comprising: cutting graphite blocks from a source of graphite; exposing the graphite blocks to an acid; and causing the graphite blocks to exfoliate into the graphene particulates.
