Synthesis of exfoliated graphite from fluorinated graphite using an atmospheric-pressure argon plasma Original Research Article

Synthesis of a stable form of exfoliated graphite (EG) is described. EG was prepared from the Graphite Intercalation Compound (GIC) fluorine–graphite using an atmospheric-pressure 27.12 MHz inductively coupled argon plasma. The fluorinated graphite dust is continuously injected into the argon plasma (5000–8000 K), and collected. Raman spectroscopy and scanning electron microscopy (SEM) images are used to identify nanotubular structures at the terminals of the EG graphite sheets.
