%X We synthesized KC8 by simply mixing molten potassium and graphite at 180 °C under inert atmosphere. The KC8 showstypical shiny bronze color, Raman characteristics and XRD pattern of an efficiently intercalated stage 1 GIC, and is ofsufficient quality to produce fully exfoliated graphenide solutions in tetrahydrofuran (THF) and subsequently single layer graphene in water as “eau de graphene” (EdG). The evolution of absorption and Raman spectroscopic signatures of the EdGas a function of processing conditions give key indications on the number of layers of the graphene flakes dispersed in EdG.
