TL;DR

This paper reports the first observation of anomalous conductivity in vinylene-vinyl chloride copolymer films, providing new insights into resistivity measurement methods for such polymer composites.

Contribution

It introduces the first demonstration of anomalous conductivity in these copolymer films and suggests new resistance measurement approaches over traditional resistivity indicators.

Findings

Anomalous conductivity observed in copolymer films.

Traditional resistivity indicators should be replaced by resistance measurements.

Resistivity of polymer composites cannot be calculated as usual.

Abstract

Manifestations of anomalous conductivity in polar dielectric films is demonstrated for the first time on samples of copolymer of vinylene and vinyl chloride, as was previously observed on modified PVC samples. On the base of these experimental results important new insights into the physical sense of traditionally used in these conditions specific resistivity indicators, both volume and surface, should be replaced by transverse and longitudinal resistance (according to polymer film surface) respectively, because the specific resistivity of polymer composite does not permits to calculate as usual the resistance of sample of arbitrary form..
