Description
Summary:The electric properties of the systems based on polyethylene glycol (PEG), carbon nanotubes (CNT) and laponite is studied using methods of impedance spectroscopy and optical microscopy. It is rotined that at introduction to the system of organo-modified laponite (OLP) leads to the shift of the percolation threshold to the area of lower concentrations of CNT. The modeling of impedance spectrums by the method of equivalent circuits is conducted for the systems based on PEG. It is set that the introduction of OLP more than 0,4 % in the system results in the considerable decrease of electrical conductivity. This effect is explained that the platelets of OLP hinder the formation of direct contacts between nanotubes.
