frequency, time, temperature etc. along with the dynamic mechanical properties of
the nanocomposites are thoroughly investigated.
For better performance the fillers must have good interfacial interaction with the
rubber medium. This is a matter of great importance and Sadasivuni and Grohens
have addressed the nonlinear viscoelasticity of rubber reinforced nanoplatelets
based on such molecular interactions existing in the system. The filler–filler and
filler–rubber interactions are studied with the help of rheology and certain theories.
For this the nonlinear stress response of rubbers and its composites to an applied
strain is noted and it is found that the 2D filler particles increase the level of
viscometric properties. Here in this chapter the readers will get a basic knowledge
about an important behavior of rubber nanocomposites which is known as Payne
effect.
Chapter 4 investigates the rheological and the dynamic mechanical properties of
rubber nanocomposites filled with spherical nanoparticles, like POSS, titanium
dioxide, and nanosilica. Here also the crucial parameter of interfacial interaction
in nanocomposite systems under dynamic-mechanical conditions is discussed.
After discussing about filled mono-matrix medium in the first three chapters, the
next chapter gives information about the nonlinear viscoelastic behavior of rubber–
rubber blend composites and nanocomposites with fillers of different particle size.
Here in Chap. 5 we can observe a wide discussion about the influence of filler
geometry, distribution, size, and filler loading on the dynamic viscoelastic behavior.
These specific surface area and the surface structural features of the fillers influence
the Payne effect as well. The authors explain the addition of spherical or nearspherical filler particles always increase the level of both the linear and the
nonlinear viscoelastic properties whereas the addition of high-aspect-ratio, fiberlike fillers increase the elasticity as well as the viscosity.
Effect of hybrid fillers on the nonlinear viscoelasticity of rubber composites
and nanocomposite is the subject of dialogue for Chap. 6. In addition to carbon
nanoparticles, the mineral fillers, biofillers, fibers, Nanorods, Nanocubes,
Nanoflowers, etc. are introduced with their influence on nonlinear viscoelasticity
of rubbers. This chapter is a nice survey about the synergy of fillers by Chaki
et al. A significant factor in rubber technology is its vulcanization and how it
depends on the nonlinear viscoelastic behavior of rubber is dealt with in the
following chapter. In the presence of cross-link networks, the viscoelasticity differs
and the factors influencing this phenomenon are very complex and obscure. From
this chapter the readers will get a new reading experience about the nonlinear
viscoelastic behaviors of cured rubbers with simplest mutle-networks—doublenetwork. Song’s transient double-network model, double-network formed by
twice curing and the specific cross-link network formed in metal salts of unsaturated carboxylic acids reinforced rubbers, is also introduced.
The last two chapters give emphasis to the theoretical side of the nonlinear
viscoelasticity of rubber composites. Thus an attempt to cover both experimental
and theoretical sides is done in this book and as the editors we feel we have
succeeded in it. Chapter 8 by Markovic et al. explains about a constitutive model
able to reproduce both static and dynamic material responses based on the behavior
