采用偶联剂对纳米BN颗粒进行表面处理,制备了经过表面处理的纳米BN/环氧树脂复合材料.对纳米/BN环氧树脂复合材料进行了微观形貌分析、击穿强度和空间电荷测试.结果表明:随着微米BN添加量的增加,微米BN/环氧树脂复合材料的击穿强度随之降低;随着纳米BN添加量的增加,纳米BN/环氧树脂复合材料的击穿强度先升高后降低.微、纳米BN的添加会降低直流高压电场下复合材料内的平均空间电荷密度.同时,偶联剂处理会降低纳米BN/环氧树脂复合材料在加压时的平均空间电荷密度,增加纳米BN/环氧树脂复合材料在短路时空间电荷的消散速率.
Nano-BN particles were treated by coupling agent, and the surface treated nano-BN/epoxy resin composites were compared. Their microscope morphology, breakdown strength, and space charge were analyzed and measured. The results show that with the increase of micro-BN content, the breakdown strength of the micro-BN/epoxy resin composite decreases. With the increase of nano-BN content, the breakdown strength of the nano-BN/epoxy resin composite increases at first and then decreases. The addi-tion of micro- and nano-BN can reduce the average space charge density of the BN/epoxy resin composite under DC high voltage electric field. Meanwhile, the coupling agent treatment can decrease the average space charge density of the nano-BN/epoxy resin composite during the polarization and increase the space charge dissipation rate during the depolarization.
