Properties of Epoxy Resin Composites Filled with KH560 Modified Halloysite Nanotubes

The introduction of filler into the epoxy resin has become one of the most important means to improve the electrical performance. In this work, halloysite nanotubes (HNTs) was modified by a commonly used silane coupling agent KH560, and then blended with epoxy resin to prepare epoxy composites. The successful modification of HNTs was confirmed by TGA and FTIR. The structure and performance including dielectric properties, charge dissipation, breakdown strength and flashover voltage of the as-prepared epoxy composites were investigated to reveal the structure-properties relationship.
