Electrophysical Characteristics of Composite Nonlinear Resistors Based on Polymer and Bentonite

Abstract

The current−voltage characteristics and the resistivity of composite resistors (varistors) based on a nonpolar polyethylene and bentonite (a clay mineral) were investigated. It was found that the content of composite components influences to the current−voltage characteristics and the magnitude of resistivity. It was shown that when increasing the molar content of the filler, the magnitude of resistivity decreases exponentially.
