One-Step Exfoliation Synthesis of Easily Soluble Graphite and Transparent Conducting Graphene Sheets

Easily soluble expanded graphite (see figure) is synthesized in a one-step exfoliation process that can be used for the low-cost mass production of graphene for various applications because of the simplicity and speed of the process. The graphene obtained is sufficiently expanded to be dispersed in aqueous solutions with an ordinary surfactant and in organic solvents.
