摘要
The effect of temperature on transient electrical charging current in gold metallized polyethylene tereplithalate (PET), which is a polymer of particular interest in electrical applications, was analyzed and compared with the results of previous work on aluminum metallized PET. Charging and discharging currents were measured with electrical fields ranging from 24 x 10(6) to 56 x 10(6) V/m and temperatures between 40 degrees and 140 degrees C. A model based on space charge formation was proposed. Simulated current showed good agreement with experimental current. This model allowed us to calculate space charge distribution and internal field.
