Electrical conduction mechanism of polyvinyl chloride (PVC)-polymethyl methacrylate (PMMA) blend film

Abstract

The electrical conduction mechanism in polyvinyl chloride (PVC)-polymethyl methacrylate (PMMA) blend film has been studied at various temperatures in the range 313 K to 353 K. The results are presented in the form of I-V characteristics. Analysis has been made in the light of Poole-Frenkel, Fowler-Nordheim, Schottky, log(J) vs. T plots and Arrhenius plots. It is observed that, Schottky-Richardson mechanism is primarily responsible for the observed conduction.

Schottky–Richardson, Poole–Frenkel, and Space Charge Limited Current Mechanisms in M‐Type Sr(MnTi)xFe(12‐2x)O19 Ferrite

“…There is no vertical regime or large slope (m > 2) observed in log J vs. log E plots which attributes the absence of discrete traps and existence of continuous traps. (B) Ionic Hopping: For the mechanism of Ionic Hopping, the current density at high electric field can be expressed by [35][36][37] : (5) where q is charge of an ion, a is ionic jump distance, E is applied electric field, k is Boltzmann constant, T is temperature, and J 0 is a constant.…”

“…(B) Ionic Hopping: For the mechanism of Ionic Hopping, the current density at high electric field can be expressed by [35][36][37] : The space charge and activated electrons are reduced due to reduction in traps caused by substitution of Fe 3+ ions.…”

Preparation and Characterization of Polymer Films of PMMA and its Composites

“…Developments of Polymer composites and extensive utilization of polymer materials in technology have led to importance in the field of polymer composites and also it is well known that the composites of polymer films exhibit enhanced properties than that of the constituent materials [1][2][3]. The composite materials of polymers are important to the electronic industry for its optical properties as well as for dielectric properties in the use of capacitors [4].…”
