摘要

采用热刺激电流(TSC)、表面粗糙度和傅里叶红外(FT-IR)方法研究了化学蚀刻聚合物(PPc)的烷基苯/聚丙烯(PP)复合绝缘子的电学性能和油/聚合物相互作用。将PP表面的非晶态部分溶解在硫酸中，得到蚀刻粗糙表面。在油/PPc样品上得到的TSC有四个清晰的峰。通过对油/PP(未加工)和油/PPc的TSC比较，发现PP中的杂质存在于PP表面附近，且PPc的离子阱较PP浅，表明化学刻蚀提高了聚合物表面的润湿性。换句话说，聚合物表面的化学蚀刻产生了浸渍油的最佳聚合物表面。

TSC of oil/polymer film composite insulator with chemically etched polymer film

The electrical properties and oil/polymer interaction for an alkylbenzene/polypropylene (PP) composite insulator with chemically etched polymer (PPc) were investigated with the thermally stimulated current (TSC), surface roughness, and FT-IR (Fourier transform infrared) methods. The etched rough surface was obtained by the dissolution of the amorphous part of the PP surface in sulfuric acid. The TSC obtained on an oil/PPc specimen has four clear peaks. The comparison in TSC between oil/PP (virgin) and oil/PPc revealed that impurities in PP exist near the surface of PP and that PPc has shallower ion traps than PP. It is concluded that the wettability of the polymer surface was improved by the chemical etching. In other words, the chemical etching of the polymer surface produces an optimum polymer surface for the impregnation of oil.<>
