Abstract:
Results of broadband (20 Hz-1 MHz) dielectric spectroscopy of multi-wall carbon nanotubes/polymethylmethacrylate composites with low loading of the carbon fillers (up to 0.5 wt%) are reported. The temperature behaviour of complex dielectric permittivity of MWCNT/PMMA composites with 0.25 wt% is similar to the pure PMMA polymer. However, the dielectric permittivity and electric conductivity of composites with 0.5 wt% are very high and both parameters are almost temperature independent. The high complex dielectric permittivity of these composites indicates the onset of percolation threshold. The relaxation time of β relaxation is shorter in MWCNT/PMMA composites than in pure PMMA.
