摘要
实验测试了纳米Al2 O3 填料、纳米SiO2 填料、纳米TiO2 填料对基体 (环氧树脂 )的电磁参数的影响情况。实验表明 ,纳米TiO2 填料降低了基体的磁损耗 ,对材料的电性参数影响明显。随着填料含量的增加 ,ε′r 值增大且tgδe 值也显著上升 ,其变化规律是 :TiO2 填料量每增加 2 0 % ,ε′r 值上升约 0 .2～ 0 .5 ,tgδe 值上升约 0 .0 2～ 0 .0
The effect of nanometer Al 2O 3, SiO 2 and TiO 2 fillings on the electromagnetic parameters of epoxide resin matrix was tested. The testing shows that, nanometer TiO 2 filling can cut down the magnetic loss of the matrix and has an clear effect on the electric properties of the matrix; the values of ε ′ r and tgδ e rise remarkably as the increase of the filling content.
