    Abstract

    The nanocomposites exhibit high electrical conductivity, significant third order non-linear optical behaviour and electroluminescence, while having substantially improved mechanical strength relative to the neat polymer. Since the experimental techniques are so expensive, the development of analytical models those are capable of predicting the time-dependent viscoelastic behaviour of such nanocomposites is essential. In this paper, the constitutive relation and linear viscoelastic behaviour of NTRPC are studied using methods of micromechanics and nanomechanics. First, the effects of volume fraction, aspect ratio and orientation of carbon nanotubes (CNTs), on the overall elastic properties of NTRPC are obtained through a variety of micromechanical techniques. Secondly, by incorporating the Dynamic Correspondence Principle (DCP), the elastic solution is extended to solve the related linear viscoelastic problem.
