Liquid silicone rubber (LSR) sheet samples of a commercial formulation and surface fluorinated using a F2/N2 mixture at various temperatures are studied in this work. The intrinsic DC flashover of the surface fluorinated samples is evaluated using a sheet sample/finger electrode configuration and under a stepwise increasing voltage. The tests show an increase up to 64% in the intrinsic DC flashover voltage of the LSR by the fluorination and an influence on the flashover on the fluorination temperature. ATR-IR and XPS analyses indicate that there are Si-F bonds as well as C-F bonds in the fluorinated layers. SEM shows the thickness of the fluorinated surface layers with nanostructured surfaces. Surface conductivity and potential decay measurements reveal that the fluorination caused a large increase in surface conduction, in association with fluorination temperature. The improvement in the intrinsic DC flashover is mainly attributed to the suppression of surface charge accumulation on the LSR by the increased surface conduction.

直接氟化增强液态硅橡胶直流闪络
本工作研究了商业配方的液态硅橡胶 (LSR) 片材样品,并在不同温度下使用 F2/N2 混合物进行了表面氟化。使用片状样品/指状电极配置并在逐步增加的电压下评估表面氟化样品的固有直流闪络。测试表明,由于氟化作用,LSR 的固有直流闪络电压增加了 64%,并且氟化温度对闪络有影响。ATR-IR 和 XPS 分析表明氟化层中存在 Si-F 键和 CF 键。SEM 显示了具有纳米结构表面的氟化表面层的厚度。表面电导率和电位衰减测量表明,氟化导致表面电导率大幅增加,与氟化温度有关。本征直流闪络的改善主要归因于通过增加的表面传导抑制了 LSR 上的表面电荷积累。
