电极材料对低密度聚乙烯中空间电荷的影响
Effects of Electrode Materials on Space Charge in Low-Density Polyethylene
摘要
Abstract
Abstract The effect of electrode on space charge in low-density polyethylene is investigated using the pulsed electro-acoustic （PEA） method. Commercial electrode materials are selected, for example, aluminum （A1）, brass doped plumbum（Pb）, brass doped zinc（Zn） and pure copper. The result shows that both hole and electron injecting from the electrodes into LDPE occurs; the higher work function of the electrode material, the more difficultly electron injecting; the lower work function of the electrode material, the more easily hole injecting; the AI（＋）/ pure copper （-） electrode system can effectively suppress space charge injection, and thus the increment of local field due to space charge is reduced.关键词
