用电子束辐照注入电荷包研究低密度聚乙烯中的电荷迁移率
Behavior of Space Charge Packet in Low-Density Polyethylene Injected by Electron Beam Irradiation
摘要
Abstract
The specimen was hot-pressed with polyvinyl fluoride (PVF) films on the double sides of LDPE sample, and was irradiated by electron beam to form a packet-like distribution of space charge. The experiments measured the space charge distribution in irradiated multi-layer specimens using laser induced pressure pulse (LIPP) method at fields lower than 50 kV/mm. The space charge packets were observed in irradiated low density polyethylene (LDPE) specimens double-sided with PVF films on double sides. The range of the average mobility of packets at a range of (0.17~3.01)×10?15m2/(V·s) under calibration local field. Experiments under different applied electric fields, and the relationship between charge packet migration velocity and applied field, and the relationship is in accordance with the distribution curve predicted by negative differential mobility model, these results prove that the negative differential mobility model is correctness under the lower applied electric field.关键词
