WebJan 19, 2011 · A novel method to synthesize few layer graphene from bulk graphite by mechanical cleavage is presented here. The method involves the use of an ultrasharp single crystal diamond wedge to cleave a highly ordered pyrolytic graphite sample to generate the graphene layers. Cleaving is aided by the use of ultrasonic oscillations along the wedge.
WebFeb 1, 2013 · Highly ordered pyrolytic graphite (HOPG) specimens embedded in acid-proof high-density polyethylene were treated in the acid mixture at 100 °C for between one to four days. The degree of HOPG damage could be seen by transmission and scanning electron microscopy, X-ray photoelectron and Raman spectroscopy, and X-ray diffraction.
