Laboratory Simulation of Charging of Polymers by Beams of Low-Energy Electrons

Inorganic Materials: Applied Research. 2013. Vol. 4. No. 2. P. 98-102.

Abstract—Charging of polymeric samples with grounded metal layer is studied by two main schemes of experiment. In the first scheme, a polymer film is irradiated with the low-energy electrons with energy of 20–40 keV under conditions of absence of grounded metal objects nearby. It is demonstrated that development of breakdown in the double electrical layer on the open surface of the polymer is impossible. In the second scheme, when a grounded metallic mask is placed on the surface of the polymer film in the irradiation zone, discharges are easily initiated and represent spark creeping discharges. A possible mechanism of their initiation is proposed.
