Melt blending of hybrid nanofillers with rubber matrices could make rubber nanocomposites more attractive for industrial applications. In this work, the low-amplitude dynamic shear modulus of polyisoprene rubber filled with carbon nanotubes or nano-graphite, individually or in combination with carbon black, was measured.

Abstract
Melt blending of hybrid nanofillers with rubber matrices could make rubber nanocomposites more attractive for industrial applications. In this work, the low-amplitude dynamic shear modulus of polyisoprene rubber filled with carbon nanotubes or nano-graphite, individually or in combination with carbon black, was measured. A rationalisation of the results highlighted interactive effects of carbon allotropes on the mechanical reinforcement of rubber nanocomposites. The filler-matrix interfacial area was identified as a parameter able to correlate the moduli values of different fillers, by reducing them to a common master curve.File | Dimensione | Formato | |
