The effect of fullerene C60 on mechanical and dielectrical behavior of epoxy resins at low loading
Abstract
Fullerene C60 / epoxy polymers nanocomposites with different C60 loadings (0.01-0.12 wt.%) have been prepared. Mechanical testing shows that compared with the neat epoxy, the mechanical and toughening properties of the composites are greatly improved. The addition of fullerene C60 increased the modulus of the epoxy (up to 20 %), but the glass transition temperature was unaffected. The measured impact strength was also increased, from 38 to 115 kJ/m2 with the addition of 0.12 wt.% of fullerene C60. The toughening mechanism has been discussed. Dielectric spectroscopy was used to investigate the influence of nanoparticles on the relaxation processes in the polymer matrix.
