2.3 Carbon Nanofillers
There are various types of carbon nanofillers which include carbon black, multi
walled carbon nanotubes (MWCNTs), and single walled carbon nanotubes
(SWCNTs) [27]. In this section the effect of these nano fillers on viscoelastic
behavior is thoroughly discussed. The physicomechanical properties of conductive
carbon black (CCB) filled ethylene acrylic elastomer (AEM) vulcanizates have
been reported by B.P. Sahoo et al. They have discussed thoroughly about the effect
carbon black concentration on the viscoelastic behavior of CCB-AEM
nanocomposites with respect to temperature variation. Figure 10a, b represents
the variation of storage modulus and loss modulus with temperature. It is observed
that the value of storage modulus (E
0 ) increased with increase in filler loading in the
