  • Expanded pyrolytic graphite: Structural and transport

    01/02/1970· A process has been developed for fabrication of a highly oriented expanded pyrolytic graphite (EPG) After forming a graphite bisulfate with pyrolytic graphite (PG), the material is heated to 500°C for several minutes to evolve acidic molecules and obtain expansion Xray analysis shows that the orientation density of twofold and threefold EPG is approximately the same as that for theExpanded graphite is multiporous The Ruoff group [22] in 1999 used a tip of an atomic force microscope (AFM) to exfoliate highly oriented pyrolytic graphite (HOPG), yielding a thickness of ~ 200 nm In 2010, Geim and Novoselov [1] used Scotch tape to exfoliate 1mmthick HOPG, and succeeded in yielding graphene of single or few layers Thus, the Nobel Prize in Physics was awarded to themExpanded Graphite an overview | ScienceDirect Topicspyrolytic graphite expanded pyrolytic heated approximately expanded Prior art date Legal status (The legal status is an assumption and is not a legal conclusion Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed) Pending Application number JPA Other languages Japanese (ja) Inventor Robert Farrell Mulvey OriginalJPHA Expanded pyrolytic graphite, process
