  3. Abstract:
  4. Exceptional mechanical properties of carbon nanotubes (CNTs) such as high elastic modulus, stiffness and tensile strength have made them as promising reinforcement in polymer nanocomposite systems. The characteristics of CNTs/polymer interphase region directly affect the efficiency of nanotubes for improving the nanocomposite mechanical properties. In this work, the influence of chains alignment within the interphase region on elastic response of the nanocomposite is assessed using a novel ordered-inordered approach. The applicability of the presented approach is examined by implementing the approach on a series of reported data available in the literature. The effects of CNT content, Young's modulus and thickness of the interphase region, on the Young's modulus of a homogenous nanocomposite are investigated. Interestingly, the results of the mentioned model are well in agreement with the experimental results that demonstrate efficiency of the approach
