Notes:
The steady-state current density versus applied electric field characteristics have been measured for two types of polystyrene films. Measurements were made on 1-mil biaxially oriented film and on films produced by casting from solution. The cast films ranged from 5 to 0.5 μ in thickness. The measurements of the steady-state current flowing through the films were done by two different methods. The first was the direct observation of current flowing in a circuit connected to the film which was under a potential stress. The second involved the observation of the decay of a static charge placed on the surface of a film. Both methods are handicapped by the fact that large transient currents flow for extended periods after any change is made in the experimental set up. The results indicate that at 25°C the current increases as the 3.5 power of the applied electric field when the field is greater than 8 × 104 V/cm. At fields less than 8 × 104 V/cm the current decreases more rapidly and tends to become zero.
