The electrical conduction in thick Polypropylene film with different crystalline has been studied different temperatures & at different potential gradients. In different cases the charge storage properties of a super charged BOPP film & un-oriented PP films have been studied. Now a special study on TOPP is taken. An initial study has been made of radiation induced oxidation of Polypropylene (PP) in both its additive-free form and one containing discrete amounts of stabilizer. Samples of PP were irradiated in a 60Coγ source to various doses .The field dependence of current shows that the conduction mechanism in this polymer is ion hopping. In these films the thermally stimulated charge decay and open and short circuit thermal current were measured.
