摘要

本文报道了不同填料浓度制备的纳米环氧树脂样品的对比分析结果。将波西米亚纳米颗粒分散到交联的环脂肪族环氧树脂中，在紫外照射下制备样品。介电性能，特别是空间电荷积累，被测量为纳米填料含量的函数。结果表明，填料含量对空间电荷积累和电荷迁移率影响较大。纳米填料浓度为5-7 wt%时，相对于环氧树脂基，空间电荷显著减少，负电荷载流子的迁移率增加。

Space Charge Dynamics in Nanostructured Epoxy Resin

The results of a comparative analysis performed on specimens of nanostructured epoxy resins obtained by different filler concentrations are reported in this paper. The specimens were prepared by dispersion of bohemite nanoparticles into a cycloaliphatic epoxy resin cross linked under UV. Dielectric properties, in particular space charge accumulation, are measured as a function of nanofiller content. Results indicate that space charge build up and charge mobility are affected largely by filler content. Concentrations of nanofiller of 5-7 wt% show a significant decrease of the space charge with respect to the base epoxy-resin and an increased mobility of negative carriers.
