Abstract
In this paper, epoxy/C60 (EP/C60) nanocomposites with different content were prepared. Scanning electron microscope and the Fourier transform infrared spectroscopy were employed to investigate the dispersion state of C60 and microstructure of the composites, respectively. Dielectric spectrum was measured to clarify the effects of the doped C60 on the polarization characteristics of materials. Both AC and DC breakdown strength were measured to assess the variation of the dielectric strength of the nanocomposites. Obtained results shows that the relative permittivity of the epoxy resin decreases when C60 filler with low content is doped. The AC breakdown strengths of the nanocomposites, with C60 content of 0.05 and 0.1 %, are improved which may come about because the nanoparticles act as a sort of scattering centers. The DC breakdown strengths of the nanocomposites, with filler content of 0.1 and 0.5 %, are improved due to more traps are introduced by the C60. Results of the trap distribution based on the isothermal discharge current tests shows that both the trap level and density of the resin are enhanced by the doped C60 filler.
