Epoxy nano composites were fabricated with the incorporation of nano AlN and MgO fillers to investigate their dielectric and space charge properties. Epoxy AlN nanocomposites with the addition of nano MgO have shown lower permittivity with reduced tanδ, good space charge behaviour, during poling period. Higher wt% of AlN in epoxy resinexhibited higher permittivity. The nanocomposites with AlN nanofiller have revealed higher space charge accumulation than on addition of MgO nano filler. Also, the addition of nanofillers to the base polymer has led to enhanced space charge decay performance compared to the base matrix.

添加纳米MgO对环氧树脂AlN纳米复合材料介电性能和空间电荷行为影响的研究

通过掺入纳米 AlN 和 MgO 填料制备环氧纳米复合材料,以研究它们的介电和空间电荷特性。添加纳米 MgO 的环氧 AlN 纳米复合材料在极化期间显示出较低的介电常数和降低的 tan δ以及良好的空间电荷行为。环氧树脂中较高重量百分比的 AlN 表现出较高的介电常数。与添加 MgO 纳米填料相比,具有 AlN 纳米填料的纳米复合材料显示出更高的空间电荷积累。此外,与基础基质相比,向基础聚合物中添加纳米填料已导致增强的空间电荷衰减性能。
