Conductive and Tensoresistive Properties of Flexible Polymer Compositres: Experimental Study and Modeling

In this paper, we present the experimental results on the conductive and tensoresistive properties of polymer composites containing a small amount of carbon nanotubes. The experimental results on the resistivity dependence on the mass fraction of the CNT filler were analyzed within the classical percolation model. The sensitivity of the resistivity of synthesized composites with different mass fractions of the CNT filler to the degree of their uniaxial tension in a wide range of the applied strain was experimentally investigated. All obtained results were successfully described based on statistical percolation and resistive network models taking into account the influence of stretching on the curvature of carbon nanotubes.
