▎ 摘  要

NOVELTY - Preparation of hydrophilic and high fluorine/carbon ratio fluorinated graphene involves activating free radicals of fluorinated graphene by heating so that free radicals of fluorinated graphene become active free radicals to carry out graft modification of hydrophilic acrylic monomer. USE - Preparation of hydrophilic and high fluorine/carbon ratio fluorinated graphene used as aqueous lubricating additive (all claimed). ADVANTAGE - The method effectively prepares the hydrophilic and high fluorine/carbon ratio fluorinated graphene without affecting the carbon-fluorine bond while retaining its inherent self-lubricating ability, which improves the friction performance of pure water, reduces the friction coefficient to 70% and wear rate to 82.4%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of using the hydrophilic and high fluorine/carbon ratio fluorinated graphene as aqueous lubricating additive, which involves adding 5-50 mg hydrophilic and high fluorine/carbon ratio fluorinated graphene to per 100 mL of ultrapure water and mixing.
