Theoretical analysis of electrical conductivity of polymeric nanocompositese based on oligoglycols and carbon nanotubes

Abstract

The basic theoretical models of electrical conductivity of polymer nanocomposites and their accordance to experimental results are analyzed for the systems based on polyethers and carbon nanotubes using the methods of mathematical simulation. It is set that models which do not take into account existence of percolation threshold (Rahaman-Chaki-Khastgir model and tunneling percolation model) and can’t be using for exact definition of experimental data. It is dies covered that the Fourier model demonstrates a good accordance with an experiment, however it is applicable only for the systems in which a large increase of conductivity under reaching the percolation threshold is observed, that systems with low own conductivity.
