Keywords:
percolation behavior, polymer nanocomposites, electrical conductivity, dielectric constant, carbon nanotubes
Abstract
Frequency dependences of electric and dielectric descriptions of the systems based on polyethers and carbon nanotubes (CNТ) are investigated using the method of impedance spectroscopy. It is revealed that in area of percolation transition, frequency dependences of electric and dielectric descriptions can be described within the framework of the percolation theory, using universal scaling laws. The results of modelling of frequency dependences of electric and dielectric descriptions are analysed within the framework of the intercluster polarization model and the anomalous diffusion model. It is set that the percolation behavior of the polyetherCNT systems can be described within the framework intercluster polarization model.
