采用表面改性后的金红石型纳米TiO_2与PTFE作为复合填料,将其与氟碳树脂(FEVE)结合,制备具有防污闪性能的纳米复合氟碳杂化材料,用压缩空气喷涂法将其涂覆在玻璃绝缘子基底表面形成氟碳防污闪涂层。采用红外光谱对改性后的纳米TiO_2进行表征分析,用扫描电镜、X线光电子能谱、接触角测量仪等观察和测试氟碳杂化涂层材料表面的微观结构及疏水性。研究结果表明:在TiO_2/PTFE改性复合氟碳防污闪涂层材料近表面区域上, TiO_2和PTFE之间通过化学键合作用形成具有类似乳突状的微/纳二元粗糙结构,对水静态接触角高达120°以上。涂层材料具有优良的耐水、耐化学试剂性、耐盐雾、耐漏电起痕及电蚀损性能,体...

The fluorocarbon hybrid nanocomposite with good anti-pollution flashover performance was fabricated by the surface modified nano-rutile-TiO<inf>2</inf>with PTFE as a composite filler with fluorocarbon resin (FEVE). A uniform nano-TiO<inf>2</inf>/PTFE modified fluorocarbon anti-pollution flashover coating was prepared by air spray method on the surface of the glass insulator substrate. Fourier transform infrared spectrometer was employed to evaluate the modified nano-TiO<inf>2</inf>particles. The surface microstructure and hydrophobicity of the fluorocarbon h...
