▎ 摘  要

NOVELTY - Method for producing random structure graphite intercalation compounds (GIC) involves preparing alkali metal-GIC having alkali metal intercalated between graphene layers, and making polar protic solvent to contact with the prepared alkali-metal GIC in non-oxidizing atmosphere. USE - The method is useful for producing random structure GIC which is used for preparing flaky graphite dispersion liquid (claimed). ADVANTAGE - The method produces random structure GIC which enables to prepare flaked graphite with few stacked layers and little regularity of the graphene stacked state by exfoliation treatment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for preparing flaky graphite dispersion liquid involves obtaining the above-manufactured random structure GIC, adding nonpolar solvent or polar solvent to the random structure GIC, and removing the processed random structure GIC from the nonpolar solvent or polar solvent; and (2) flaky graphite dispersion liquid obtained by the above-mentioned method.
