Anomalous conductivity dependence of plasticized PVC for different modificator "A" concentrations and film thicknesses

TL;DR

This study investigates how the electrical conductivity of plasticized PVC films varies with different concentrations of plasticizer 'A' and film thickness, revealing non-monotonic and nonlinear behaviors.

Contribution

It provides experimental data and discusses models explaining the complex dependence of PVC conductivity on plasticizer content and film thickness.

Findings

Conductivity shows non-monotonic dependence on plasticizer concentration.

Film resistance depends strongly and nonlinearly on thickness.

Models can describe the observed conductivity behaviors.

Abstract

The dependences of electrical conductivity of plasticized PVC films on mass fraction of plasticizer "A" and the film thickness are experimentally investigated. Non-monotonic dependence of conductivity on the concentration of plasticizer and strongly nonlinear dependence of the resistance of the film on its thickness are found. Possibility of construction of the models describing received results is shown and also discussed.
