In recent years, the nonlinear viscoelastic behaviors of elastomeric nanocomposites have been examined, especially for a wide range of rubbery composite (including natural rubber) materials. This chapter describes the influence of fillers and nanofillers on the nonlinear viscoelastic properties of elastomeric polyurethane systems. These filled elastomers (similar to the classic natural rubber reinforced elastomers), also exhibit nonlinear behavior called the Payne effect. The complexity of the polyurethane elastomers, where soft (SS) and hard (HS) segments are present in this matrix, cause entanglement between polymer and filler. Moreover, type, size, and geometry of the nanofiller strongly depend on the place of the dispersion into relevant segments, and powerfully influence the properties of the whole nanocomposite system. This chapter also briefly summarizes various types of techniques generally used to characterize nonlinear viscoelastic properties of polymeric materials.
