Electrical and Mechanical Behavior of Nano-Filled Polymers through Molecular Dynamics Simulations

Abstract

This report results from a contract tasking University of Minho as follows: The aim of this project is to study the evolution of the nanotube network with mechanical deformation (uniaxial, biaxial) and the subsequent impact on the anisotropy of electrical and mechanical properties of these polymeric materials reinforced with nanofibers and nanotubes. Although there is a wide range of variables of interest in the case of nano-reinforced polymers, a special focus will be given to the effects of nanofiber concentration and length as well as the much less understood role of nanofiber flexibility (persistence length/rod length <1) and initial preferential orientation. This project will improve the understanding of the mechanisms responsible for changes in electrical properties during deformation of nano-reinforced polymers.
