  • Correspondence between nonlinear viscoelastic properties and change in various networks in carbon black (CB) filled rubbers have been studied by using combined measurements of relaxation modulus and volume resistivity in wide range of filler concentrations at various shear strains. Volume resistivity in no deformation showed step-off like change which can be explained by the percolation theory. This indicates formation of contact filler network by CB particles at high filler loading. In addition, change in volume resistivity showed clear correspondence with linear-nonlinear transition in viscoelasticity. By the use of simple three networks model, contributions of contact filler, bridged filler, and entanglement networks to relaxation modulus were estimated. Furthermore, the three network model was tested from the viewpoint of temperature dependence of viscoelasticity of filled rubbers. It was found that contact filler network was dominant at higher filler concentration and bridged filler network was at lower concentration.
