Space Charge Profiles in Elastomer Sheets with Laminating Area of Vertical Direction against Electric Field Direction

In this paper, the space charge profiles in elastomer sheets with laminating area of vertical direction against electric field direction is investigated. Samples were prepared using a stereolithographic 3D printer. Sample N has no lamination. Sample H has horizontal laminating direction against sample surface. Space charge distribution was measured using the pulsed electro-acoustic system. The DC conduction current was measured by using a current integration meter. The accumulated positive charge amount near the anode in sample H was found to be larger than that in sample N. It is considered that a number of positive charges raised via the Pool Frenkel mechanism accumulated at the laminate interface in sample H.
