Features of Percolation Behavior of Systems Based on Polyethers and Carbon Nanotubes with Addition of <i>LiClO₄</i>

CZU 539.2:537.31

The research of electric properties of the systems based on polyethers and carbon nanotubes (CNT) with the addition of an inorganic salt of LiClO₄ is conducted using the method of impedance spectroscopy. The percolation thresholds are determined by the standard percolation theory for the nanofilled systems based on polyethylene glycol and polypropylene glycol, which were 0.45% and 0.5%, respectively. It is foud that for the polyether-CNT-LiClO₄ systems two percolation thresholds are observed. The modified percolation model, which takes into account the existence of two percolation transitions, is offered.
