NEXAFS study of various graphite fluorides
I.A. Zhdanov

The aim of this work is to use the method of X-ray absorption spectroscopy NEXAFS with synchrotron radiation (SR) for getting information on the atomic and electronic structure of graphite fluorides (C2F)n, (CF)n and similar fluorocarbon compounds.
All measurements have been performed at the Russian-German beamline at the BESSY II  and at the D1011 beamline of the electron storage ring MAX-2. The C 1s and F 1s NEXAFS spectra of (CxF)n (x=2.5, 2 и 1), C20F42, PTFE as well as of reference samples (HOPG, nanodiamonds) were obtained in the total electron yield mode and in the partial electronic yield mode.
The comparative analysis of the C 1s and F 1s NEXAFS spectra of reference samples (HOPG, graph-CNDs, ND, WGF) with those of large panel of fluorinated graphites ((CxF)n, x=2.5, 2 and 1) of different structures and C-F bonding according to their synthesis at high or room temperature, PTFE and C20F42 allows us to get important information about the chemical bonding in the graphite fluorides and similar fluorocarbon compounds.
