Specifics of percolation behavior in the polyether–carbon nanotube systems doped with LiClO4

Resumo

The electrical properties of the polyether/carbon nanotube (CNT) systems doped with LiClO₄ inorganic salt are studied via impedance spectroscopy. The percolation thresholds are evaluated in the context of the standard percolation theory for the nanofilled systems based on polyethylene glycol and polypropylene glycol, being 0.45 and 0.5%, respectively. Two percolation thresholds are observed for the polyether–CNT–LiClO₄ systems. A modified percolation model with consideration of two percolation transitions is proposed.
