摘　　要：绝缘材料的沿面闪络特性受许多因素的影响,如表面粗糙度、纳米填料和化学官能团。本研究以聚酰胺网为支架,以疏水纳米二氧化硅颗粒为改性材料,基于溶解和再凝固的处理方法,将纳米填料嵌入聚酰胺网中。通过改变网孔尺寸确定微观结构,利用氟化纳米颗粒改变复合表面化学基团。研究了微结构/纳米填料对沿面闪络的耦合效应,同时赋予了材料超疏水性能。结果表明:当聚酰胺网目数为300目时,SiO_(2)/聚酰胺网超疏水复合材料具有最佳的抗闪络性能,闪络电压提高20%。The surface flashover of insulating material is affected by many factors,such as surface roughness,nano fillers,and chemical functional groups.In this study,polyamide mesh was used as support and hydrophobic nano silica particles were used as modified materials.Nano fillers were embedded into polyamide mesh by the treatment method of dissolution and resolidification.The microstructure was determined by changing the mesh size,and the chemical groups on the composite surface were changed by fluorinated nanoparticles.The coupling effect of microstructure/nano filler on surface flashover was studied,and the material was endowed with superhydrophobic properties.The results show that with the polyamide mesh of 300 mesh,the composite has the best anti flashover performance,and the flashover voltage was increased by 20%.
