摘要：

Results of broadband (20 Hz-1 MHz) dielectric spectroscopy of multi-wall carbon nanotubes/polymethyl-methacrylate 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 13 relaxation is shorter in MWCNT/PMMA composites than in pure PMMA.
