摘要

纳米填料对环氧树脂介电性能的影响已被研究多年。然而，在相同的纳米颗粒成分下，关于纳米颗粒对复合材料介电性能的影响，有一些相互矛盾的报道。由于纳米颗粒的团聚和分布，不同的加工工艺会导致纳米颗粒的分散和复合材料的介电性能不同。本文研究了纳米二氧化硅/环氧复合材料的介电性能与纳米粒子分散度之间的关系。采用图像J和数学方法定量分析了介电常数、电晕电阻、击穿强度和色散等介电性能。发现了介电性能与纳米粒子色散之间的一些规律。

The relationship between dielectric properties and nanoparticle dispersion of nano-SILICA/Epoxy composites

The effect of nano-fillers on dielectric properties of Epoxy has been studied for years. However, with the same nano-particles component, there are some conflicting reports regarding the effect of nano-particles on the dielectric properties of composites. The different processing will result in different dispersion of nano-particles and different dielectric properties of composites as a result of the agglomerate and distribution of nano-particle. Here we investigate the relationship between dielectric properties and nano-particle dispersions of nano-Silica/Epoxy composites. The dielectric properties including permittivity, corona-resistance, breakdown strength and dispersion are quantitative analyzed by Image J and mathematical method. Some rules are discovered between dielectric properties and nano-particle dispersion.
