Water exfoliated graphite saturation

Exfoliated graphite could sorb a small amount of water for example, the capacity of our exfoliated graphite with 6 kg/m bulk density was about 1.8 kg/kg, and no difference in sorption capacity was detected among distilled water, tap water, and seawater, as shown in Table 4.3. Even after saturation with water, the exfoliated graphite floated on the water surface. 

When A-grade heavy oil was dropped onto one end of this water-saturated exfoliated graphite, water was observed to come out from another end of the...

In the case of carbonized hr fibers, water adsorption depends strongly on the type of water, as shown in Table 4.3 the fibers adsorb a relatively large amount of distilled water, but only a small amount of seawater adsorption is much more for distilled water and much less for seawater than for exfoliated graphite. Fir fibers carbonized at 900°C adsorbed a little less water than those carbonized at 380°C. After the fir fibers were saturated with distilled water, heavy oil was dropped...
