| Abstract: Expandable graphite intercalated by ammonium phosphate (AP) or ammonium polyphosphate (APP) was prepared by direct intercalation and two-step method, respectively. The products from two-step method show higher expansion volume, more weight increase and more weight loss after expansion, suggesting that the two-step method is a favorable method for preparation of APP intercalated EG. XRD provides convincing evidence for successful formation of APP-EG by showing strong diffraction peak at much lower 2θ angle. Scanning electron microscopy (SEM) with energy dispersive X-ray Spectroscopy (EDS) gives more evidence for intercalation of APP in the graphite layers. |
