Due to their outstanding properties, carbon nanotubes (CNTs) and carbon nanofibers (CNF) are considered as the material of the 21st century. Besides single wall nanotubes (SWNT) and multi wall nanotubes (MWNT), also double wall nanotubes (DWNT) and chemically functionalized nanotubes are commercially available. In addition also several carbon nanofibers distinguished e.g. as heringbone or platelete widen the material's diversity. Recently, also single graphite layers, kown as graphene, arouse the curiosity of the scientific community and are synthesized and processed for first applications.
