ESEG was prepared from a fluorinated graphite intercalation compound (FGIC) - C2F∙nClF3 containing inorganic volatile intercalating agent ClF3. The severe expanded state, together with high specific surface area of the ESEG can give us essential material properties for dispersing easily the ESEG in the solution. ESEG suspension prepared in several orgarnic solvents without any surfactant and water with common surfactants using sonication process. We will demonstrate that ESEG could be considered as the preferable reinforcing filler in polymer matrices. Furthermore, without chemical modification, ESEG provide effective anchoring sites for strong bonding with polymers.
