几个氟化聚乙烯表面的研究已经证明，氟化反应可以有效地防止电荷注入聚乙烯。因此，本文探讨了氟化电极对聚乙烯空间电荷行为的影响。本文采用激光-压力波传播法（PWP）测量了聚乙烯内部空间电荷的分布，并改变了电极放电时间和放电温度。实验结果表明，测量的同质电荷注入增加的聚乙烯，氟化聚乙烯电极是热压。还进行了衰减全反射-红外（ATR-IR）光谱和扫描电子显微镜（SEM），揭示了聚乙烯和电极之间的界面上的氟化层的聚乙烯电极阻止杂质进入聚乙烯。测量的空间电荷分布，即平面平均量，也揭示了杂质的产生，因为观察到异质电荷的形成。由于这些杂质被阻挡，同时电极的同质电荷注入保持不受影响，从而测量的表观电荷大大增加。
Several fluorinated polyethylene surface studies have proved that the fluorination reaction can effectively prevent charge from being injected into polyethylene. Therefore, this paper explores the influence of fluorinated electrode on space charge behavior in polyethylene. In this study, the space charge distribution inside polyethylene is measured by laser-PWP (Pressure Wave Propagation) method while altering electrode fluorination duration and fluorination temperature. The experimental results show that measured homocharge injection is increased in polyethylene to which a fluorinated semiconductive electrode is heat pressed. Attenuated Total Reflectance-Infrared (ATR-IR) spectroscopy and Scanning Electron Microscope (SEM) are also performed, revealing that the fluorinated layer of semiconductive electrode on the interface between polyethylene and electrode block impurities from entering polyethylene. The measured space charge distribution, being the planar average amount, also reveals impurity generation since heterocharge formation is observed. As such impurities are blocked, in the meantime the electrodes' homocharge injection remains un-affected, thereby the measured apparent charge is greatly increased.
