ABSTRACT: In this report, we present fundamental DC conduction mechanisms of pol-yvinyl difluoride/nano-zinc oxide (PVDF/ZnO) composite films. Nano-composite films of zinc oxide in the PVDF matrix have been fabricated via a solution casting method. Space charge limited conduction (SCLC) was found to be a prominent conduction mechanism in higher voltage region and Schottky- Richardson mechanism was a possible conduction mechanism in a higher temperature region. DC activation energy for composites was found to decrease with increasing concentration of ZnO nanoparticles and reduced graphene oxide (RGO) with 1.41 eV (9.9 wt%), 1.04 eV (33.33 wt%), and 0.95 eV (33.33 wt% RGO), respectively.
