Notes:
Polycarbonate - carbon nanofibers, containing various concentrations of filler rangingfrom 0 % to 10 % wt. have been investigated by electron spin resonance. The as obtained electronspin resonance spectra are complex due to the overlap of several resonances originating from theconducting electrons delocalized over the metallic domains of nanotubes, from the free radicalsgenerated within the polymeric matrix during the processing step, from insulating graphite particles,and from catalyst residues (observed as magnetic impurities).The effect of the filler on the resonance line shape is analyzed in detail. The shape of resonancespectrum demonstrates that the resonance line located near g=2.00 originates from conductingelectrons delocalized over the metallic domains of nanotubes. Thos line was accurately fitted by aLorentzian line shape
