Electrical Conductivity Study of Pvc: Pmma Polymer Blend Thin Film Thermoelectret Using Al, Cu And Ag Electrodes

Abstract

The goal of this study is to determine the electrical conductivity of the PVC: PMMA polymer blends in thin film thermoelectret form using Al ,Cu and Ag as electrode material at various temperatures in the range 323K to363K. Al-film-Al, Al-film-Cu, and Al-film-Ag structure has been investigated for presenting the results in the form of I-V characteristics. Analysis on various results has been made by interpretation of Poole-Frenkle , Fowler-Nordheim ,Schottky ln J vs T plots, and Richardson plots ,which suggests that Schottky Rechardson mechanism are primarily responsible for the observed conclusions.
