▎ 摘  要

NOVELTY - Dissolving (M1) carbon material involves: providing a carbon material selected from graphite, graphite oxide, oxidized graphene nanoribbons or reduced graphene nanoribbons; and dissolving the carbon material in a solvent to form a solution, where the solvent comprises at least one superacid. USE - For dissolving carbon material (where the carbon material selected from graphite, graphite oxide, oxidized graphene nanoribbons and reduced graphene nanoribbons) used in the article such as film and fiber (all claimed). ADVANTAGE - The method produces high-concentration solutions carbon material. Such high-concentration solutions permits ready processing of carbon material into various articles such as films, fibers, polymer composites and shaped articles containing primarily or solely carbon material. The method does not chemically modify or damage the carbon material such that the beneficial properties of the pristine carbon materials can be maintained. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a solution comprising a solvent containing at least one superacid; and a carbon material dissolved in the solvent.
