Abstract
The thin films of polystyrene obtained in an electrical discharge present a value of tan δ higher than that of traditional polystyrene films. It appears that oxygen is one of the factors bringing on this failure. A noticeable improvement of loss factor can be obtained either by addition of antioxydant or by reducing the electrodes spacing.
