Percolation transition and inversion of conductivity hysteresis upon cooling of electroconductive polymer composites
Volkov A. Yu. , Sal'nikov V. A., Pronin A. A.
The possibility of obtaining a thermogenic percolation transition upon cooling of polymer composites with initial concentration of the electroconductive filler far below the percolation threshold is demonstrated. The obtained data are in qualitative agreement with the Muenchhausen ramrod model, which predicts the existence and peculiarities of this low-temperature transition. A change in the character of the conductivity hysteresis is observed when the composite is cooled below the percolation transition temperature.
