The surface flashover is affected by many factors, such as surface roughness, nanofillers and chemical functional groups. In this research study, polyamide mesh was utilised as a scaffold to systematically study the synergistic effect of micro structure/nanofiller/superhydrophobicity on the surface flashover. Based on the dissolution and resolidification method, nanofillers were partially embedded into the mesh fabrics. Here, Al₂O₃ nanoparticles were used as a typical non-conductive nanofiller, and carbon nanotubes were used as a typical conductive nanofiller. Moreover, the micro structure was determined by altering the mesh size, and chemical fluorination was utilised to change the surface chemical group. It was found that the polyamide mesh with 300# demonstrated best anti-flashover properties. Chemical fluorination could effectively improve the flashover voltage. By further adjusting the ratio of Al₂O₃ to carbon nanotubes, the flashover voltage can be increased by up to 30%.

微结构/纳米填料/超疏水对表面闪络的协同作用

表面闪络受许多因素影响，例如表面粗糙度、纳米填料和化学官能团。在这项研究中，聚酰胺网作为支架系统地研究了微结构/纳米填料/超疏水性对表面闪络的协同作用。基于溶解和再固化方法，纳米填料被部分嵌入网眼织物中。这里，Al ₂ O ₃纳米粒子被用作典型的非导电纳米填料，碳纳米管被用作典型的导电纳米填料。此外，通过改变网孔尺寸确定微观结构，并利用化学氟化来改变表面化学基团。结果发现，具有 300# 的聚酰胺网格表现出最佳的防飞弧性能。化学氟化可有效提高闪络电压。通过进一步调整Al ₂ O ₃与碳纳米管的比例，闪络电压最多可提高30%。
