研究了聚酰胺纳米复合材料与两种聚酰胺微米复合材料的局部放电降解性能。在IEC（B）电极配置下将此类材料暴露于PD，以评估PD电阻。使用扫描电子显微镜，原子力显微镜，和机械表面轮廓仪的表面粗糙度进行了比较。它的结论是，聚酰胺纳米复合材料是更耐PD比微复合材料，和纳米效应将对PD降解。纳米效应包括填料-基体结合、填料间空间、形貌和介观相互作用。
Partial discharge (PD) degradation was investigated to compare polyamide nanocomposites with two kinds of polyamide microcomposites. Such materials were exposed to PDs under the IEC(b) electrode configuration for evaluation of PD resistance. Comparisons were made as to the surface roughness using a scanning electron microscope, an atomic force microscope, and a mechanical surface profilometer. It is concluded that the polyamide nanocomposite is more resistant to PDs than microcomposites, and that nano-effects would work against PD degradation. The nano-effects include filler-matrix bonding, inter-filler space, morphology, and mesoscopic interaction.
