研究了炭黑负载聚乙烯(PE)复合材料在室温和高于PE熔点170℃时的电阻率随温度的变化规律。照射剂量不同。在给定的负载水平下，室温下的辐照相当于对低阻固体三相复合体系的能量处理，而在高温下相当于对高阻粘性两相体系的能量处理。辐照条件对电学响应温度的影响较为复杂。用差示扫描量热仪、凝胶分数和广角X射线衍射仪对所得复合材料的结构进行了分析。然后通过与未辐照样品的结果进行比较，对结果进行了讨论。©2000 John Wiley&Sons，Inc.《应用理工学院学报》77：494-499,2000
The temperature-dependent resistivity behavior of carbon black–loaded polyethylene (PE) composites irradiated both at room temperature and 170°C above the PE melting point was studied. The irradiation doses were varied. At a given loading level, irradiation at room temperature corresponded to an energy treatment on a low-resistive, solid, three-phase composite system, while at a high temperature it corresponded to a treatment on high-resistive, viscous, two-phase system. The irradiation condition had a complicated influence on the electrical response to temperature. The resulting composite structure was analyzed by using differential scanning calorimetry, gel fraction, and wide-angle X-ray diffraction. The results were then discussed by comparing them with those of the unirradiated sample. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 494–499, 2000
