Schottky -Richardson Mechanism in Oxalic Acid Doped (PVC-PMMA) Blends

Dakre A. B | Lamdhade G. T

Abstract: We have measured the electrical conductivity of Oxalic acid doped Polyvinyl Chloride (PVC) - Polymethyl Methacryalate (PMMA) blends at temperatures (313K - 373K). The current voltage characteristic of blends does not obey the power law and there is absence of ohmic conduction. The electrical conduction mechanism discussed by various models such as PooleFrenkel; FowlerNordheim; Schottky ln (J) Vs T plots; Richardson and Arrhenius Plots. Out of this; Schottky - Richardson mechanism is conscientious for the observed conduction mechanism in the Polyblends
