Carbon black nanoparticle-reinforced polyisoprene applied in electric heating elements and resistors as thermodynamically inactive materials for a high dielectric constant (>1000) has been studied. The dissipation factor (tanS) of this carbon black nanocomposite was high (Xu and Wong, 2005). However, improving the dispersion of the nanoparticles in polymer lowers the percolation threshold of composites (Raza et al., 2012 Sumfleth et al., 2011). The electrical conductivity of rubbery epoxy/carbon black nanocomposites at 8 wt% filler loading was 2 x 10 S/m, which matched the criterion of electrical conductivity for electrostatic applications (10 S/m) (Ali Raza et al., 2012 Knite et al., 2004 Sasha Stankovich et al., 2006).
