Abstract

The influence of addition of polycyclic compounds into LDPE upon electrical tree initiation was investigated to demonstrate the fundamental role of the aromatic compound in the tree initiation process. Five kinds of the polycyclic compounds were used in this study; naphthalene (Np), anthracene (An), 9,10-bromoanthracene (Br-An), tetracene (Te) and pentacene (Pn). The experimental results indicated that the tree initiation voltage (TIV) depend on the kind of polycyclic compounds added to LDPE. TIV for ldquoPE/Anrdquo is the highest, and is about 3.5 times higher than that for ldquoPErdquo (without additive). TIV for ldquoPE/Br-Anrdquo is the secondly highest. However, the scatter for ldquoPE/Br-Anrdquo is much wider than that for ldquoPE/Anrdquo. TIVs for ldquoPE/Terdquo and ldquoPE/Pnrdquo are not significantly higher than that for ldquoPErdquo. The addition of ldquoNprdquo has almost no effect on the increase in TIV. The mechanisms for the increase in TIV are discussed based on the experimental results with the pi-electron effects for absorption of kinetic energy of the hot electron and observations of deposit of the additive in the test materials by AFM and SEM.

多环化合物添加剂在抑制LDPE电树生成中的作用

研究了在LDPE中加入多环化合物对电树引发的影响，以证明芳香化合物在树引发过程中的基本作用。本研究使用了5种多环化合物;萘(Np)、蒽(An)、9,10-溴蒽(Br-An)、四烯(Te)和五苯(Pn)。实验结果表明，树起始电压(TIV)与加入到LDPE中的多环化合物种类有关。ldquoPE/ andrquo的TIV最高，约为ldquoPErdquo(无添加剂)的3.5倍。ldquoPE/ br - andquo的TIV是第二高的。然而，ldquoPE/ br - andrquo的散点比ldquoPE/ andrquo的散点宽得多。ldquoPE/Terdquo和ldquoPE/Pnrdquo的tiv值不显著高于ldquoPErdquo。ldquoNprdquo的加入对TIV的增加几乎没有影响。根据pi电子效应对热电子动能吸收的实验结果以及AFM和SEM观察到的添加剂在测试材料中的沉积情况，讨论了TIV增加的机理。
