Carbon Nanofiber: nanofiber composed of carbon. A nanofiber is a nano-object with two similar external dimensions in the nanoscale and the third dimension significantly larger (ISO/TS 80004-3:2010):

  • Graphitic Nanofiber: carbon nanofiber composed of graphene multilayer structures. Note: Graphene layers can be any orientation with respect to the fiber axis without long-range order.
