Effect of Double Networking on Non-Linear
Viscoelasticity of Elastomers
Yukun Chen and Chuanhui Xu
Abstract The nonlinear viscoelastic behavior of cured rubber is quite different
from that of uncured compound, since the presence of crosslink networks. The
factors for the influence of the crosslink networks on the nonlinear viscoelastic
behaviors of cured rubbers are very complex and obscure. One of the reasons is that
the crosslink networks may be consisted of several different types of networks.
However, there are few literatures reporting the nonlinear viscoelastic behaviors of
cured rubbers with mutle-networks. We reviewed the literatures dedicated to the
topic of the non-linear viscoelasticity of simplest mutle-networks—double-network
and summarized the useful information as much as possible in the present paper.
Song’s transient double-network model, double-network formed by twice curing
and the specific crosslink network formed in metal salts of unsaturated carboxylic
acids reinforced rubbers are introduced in detail.
Keywords Crosslink rubber • Double-network • Non-linear viscoelasticity
1 Introduction
The nonlinear viscoelastic behavior of elastomers is usually related to their inner
structure interaction, namely, the interaction between the matrix molecules, the
interaction between the matrix molecules and fillers, and the interaction between
the fillers. Of course, the effect of characteristics of the inner structure on the
nonlinear viscoelastic behavior of elastomers cannot be ignored, since it is also
related to portion of the energy dissipated during dynamic deformation. For
instance, the filler parameters are important which influence the dynamic properties
of rubber compounds, dynamic hysteresis in particular, as well as their temperature
