Definitions

  • the present invention relates to a process for the functionalization of carbon fibers with the vapor of nitric acid, so modified carbon fibers and their use.
  • An objective of these treatments may also be the purification, cutting and opening of the carbon nanofibers (Liu, J. et al., 280: 1253-6 (1998)).
  • a simple but highly effective method of functionalizing carbon fibers by treatment with nitric acid vapor is provided, thereby avoiding the problematic separation by filtration.
  • nitric acid vapor a significantly larger amount of oxygen species on the surface can be detected by X-ray photoelectron spectroscopy (XPS).
  • XPS X-ray photoelectron spectroscopy
  • Carbon nanofibers more preferred for the invention are obtained by methods basically described in the following references: The production of carbon nanotubes with diameters smaller than 100 nm is described for the first time in EP 205 556 Bl. For the preparation here light (ie, short- and medium-chain aliphatic or mononuclear or dinuclear aromatic) hydrocarbons and an iron-based catalyst are used, are decomposed at the carbon carrier compounds at a temperature above 800-900 0 C.
  • the carbon fibers may be positioned in the vapor stream with a fixture 12.
  • This holding device may be, for example, a sieve, grid or even rust.
  • FIG. 5 shows the comparison of the TPD cleavage profiles of carbon nanofibers during treatment by means of HNO 3 gas phase, NO 2, NO 2: O 2 (1: 1) and HNO 3 liquid. All treatments were carried out for 3 hours each. The graphics are normalized to 1 g carbon fiber.
