▎ 摘  要

NOVELTY - Preparing oil-soluble fluorinated graphene involves adding the graphite fluoride into the high-pressure reaction kettle, adding dispersant and auxiliary agent, stripping medium and supercritical intercalation graphite fluoride in mass ratio of 0.1-10:1, presetting the temperature and pressure in the reaction kettle to the preset critical value, stripping the supercritical intercalation medium and starting circulating flow, inserting layer peeling to be supercritical medium flow in cycle time reaches a predetermined value, where reaction pressure is reduced to normal pressure. USE - Method for preparing oil-soluble fluorinated graphene (claimed). ADVANTAGE - The method enables to prepare oil-soluble fluorinated graphene has material specific gravity, fluoride mild supercritical fluid and enhanced degree of fluorinated graphene. DETAILED DESCRIPTION - Preparing oil-soluble fluorinated graphene involves adding the graphite fluoride into the high-pressure reaction kettle, adding dispersant and auxiliary agent, stripping medium and supercritical intercalation graphite fluoride in mass ratio of 0.1-10:1, presetting the temperature and pressure in the reaction kettle to the preset critical value, stripping the supercritical intercalation medium and starting circulating flow, inserting layer peeling to be supercritical medium flow in cycle time reaches a predetermined value, where reaction pressure is reduced to normal pressure. The obtained product is subjected the boost process, controlled and reduced time to control the graphene layers to obtain the oil-soluble fluorinated graphene. The supercritical intercalation stripping medium is sulfur hexafluoride, dispersant and auxiliary agent, which is lubricant base oil.
