Abstract

Investigation of the decay characteristics of trapped charges in polymers is of current interest. ^1–6 In most studies polymer foils are charged with corona or thermal methods up to charge densities of 10 ⁻⁷ C/cm ² , and depolarized at rising temperatures. In the present report we discuss results of charge decay from foils charged up to 10 ⁻⁶ c/cm ² with a breakdown method, or with an electron beam. Materials studied were 12.7 and 25.4 μm foils of polyethylene terephthalate (PET), polyfluoroethylenepropylene (PEP), and polytetrafluoroethylene (TFE). The foils were either nonmetallized or metallized on one surface.
