在这里，我们报告了一种环氧-层状硅酸盐纳米复合材料的绝缘性能，该复合材料是通过在环氧树脂中分散改性层状硅酸盐而制备的。这种纳米复合材料具有通过将树脂分子插入到每个硅酸盐层之间的空隙中而形成的插层结构，并且比没有层状硅酸盐填料的环氧树脂具有更高的绝缘击穿强度。纳米复合材料中具有许多分支的电树状进展似乎导致绝缘击穿强度的增加。这些结果表明，它们有可能作为绝缘材料应用于重型设备。
Herein, we report the insulation properties of an epoxy-layered silicate nanocomposite, prepared by dispersing modified layered silicates in an epoxy resin. This nanocomposite has an intercalated structure formed by the insertion of resin molecules into the spaces between each silicate layer, and it has higher insulation breakdown strength than that of an epoxy resin without layered silicate fillers. The electrical treeing progress, with many branches, in the nanocomposite seemed to result in an increase in insulation breakdown strength. These results suggest the possibility of their application as insulating materials in heavy apparatus.
