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.
