Influence of dynamic shear action on filler phase of carbon black (CB) filled and graphene (rGO) filled polydimethylsiloxane (PDMS) was comparatively studied by electrical resistance-rheological behavior simultaneous measurements technology. The relationship curves of both storage modulus-filler content and electrical resistivity-filler content show typical percolation behavior. It is demonstrated a percolated rGO network structure in rGO/PDMS suspension with the content of 1.5%, which is much less than 3.5% in CB-based suspension. The results of electrical resistance-rheological behavior simultaneous measurements show that rGO networks, which is very sensitive to dynamic shear action, start to be destroyed even suffered to small strain (γ>0.3%) shear. The collapsed rGO network appear difficult to reform even with heating at 100 ℃ for 5000 s. However, the rapid recovery behavior of collapsed CB network appear immediately in the subsequent decreased strain sweep.
