Abstract

We are interested in the interfacial phenomena concerning breakdown mechanism in solid dielectrics. We have been researching the effect of ionic impurity on space charge distribution and electric properties in filled epoxy resin and polyimide resin containing carbon. We have studied on the factors for hetero space charge accumulated near the electrodes by means of comparing the result of ionic analysis with the result of space charge behavior in high polymer this time. And we have guessed that hetero charge (positive charge) accumulated near the cathode are proton (H⁺) separated from organic acid, and negative charge accumulated near the anode are various -COO^- ions separated from organic acid
