Two types of layers which differ in the arrangement of the acid anions and acid molecules and which also have different thicknesses were found on electro–chemical intercalation of perfluorobutanesulfonic acid in graphite. Such a phenomenon, which occurs in the first and second stage of the graphite salt, has never been observed in other graphite compounds. It is of interest, inter alia, in connection with the packing of alkyl chains in crystalline polymers, especially poly (tetrafluoroethylene), and with respect to the investigation of phase transformations in quasi two‐dimensional molecular assemblages.
