Glow discharge polymerization in the CF3Br/CH4 system

Summary Glow discharge polymerization in the system of the CF₃Br/CH₄ mixture was investigated by infrared spectroscopy and ESCA.Surface energies of polymers from the CF₃Br/CH₄ mixture decrease as increasing the concentration of CF₃Br in the mixture, but the value of surface energy is not as low as that of polymers from CF₄/CH₄ mixture and from CF₂=CF₂. Polymers from the CF₃Br/CH₄ mixture possess a large amount of bromine as well as fluorine, and consist of five structural features which was determined by deconvolution of the C_ls level spectra. A relative concentration of each structural feature was also discussed in comparison with that for polymers from the CF₄/CH₄ mixture and CF₂=CF₂.
