Nonlinear Viscoelasticity of Two Dimensional Filler Reinforced Rubber Nanocomposites

This chapter describes the effect of two dimensional filler particles on the non-linear viscoelastic properties of elastomer nanocomposites. The distribution of nanosized fillers and the existing interactions—nanofiller-nanofiller and nanofiller-matrix—in the nanocomposite systems are crucial for understanding their behavior under dynamic-mechanical conditions. The non-linear stress response of rubbers and its composites to an applied strain is very significant in formulating the material applications. The reported nonlinear viscoelastic properties for composites of two dimentional fillers such as clay and graphene in different elastomer matrices are critically reviewed. Rheological and dynamic mechanical properties of elastomer nanocomposites are mainly dealt with. The addition of 2D filler particles alters the nonlinear behavior of the loss factor with strain mostly by increasing the level of viscometric properties. Moreover the addition of high-aspect-ratio, sheet-like fillers increase the elasticity as well as the viscosity.
