Description
γ-irradiation of a large dose (0.5-4 MGy) leads to the breaking of macromolecular chain and the rising of group density of phenyl with oxygen in (polyethylene terephthalate) (PET) films. The detrapping current of trapped charge carriers and the depth of trapping level of irradiated PET electrets increase with increasing irradiation dose. Due to the change of molecular structure, the kinds of structural defect rise results in increasing of the number of discrete trapping levels (from two of amorphous to four of R-5)
