摘要：

Electrochemically intercalated graphite with H2SO4 was thermally expanded at 1000 degrees C. Exfoliated samples of GIC-H2SO4 with different times of expansion revealed different expansion volumes. Both the surface area and the chemical character of samples also depend on the exfoliation time. A low density of the exfoliated graphite is demanded for the oil sorption. The oil sorption is restricted by the surface area and the bulk density.
