| 摘要: |
| 本文对比分析了传统法和微波辅助法合成的Mg(OH)2对所制备的纳米MgO晶粒尺寸和表面形貌的影响,以及纳米MgO不同制备方法对MgO/LDPE纳米复合材料空间电荷、体积电阻率及直流击穿场强的影响.结果表明,传统法制备的纳米MgO晶粒尺寸为22.74 nm,微波辅助法制备的纳米MgO的晶粒尺寸为12.76 nm, MgO质量分数为2%时有效降低了复合材料内部空间电荷的积聚,对复合材料的体积电阻和击穿场强均有提高. |

| Abstract: |
| This article compares the traditional method with the microwave-assisted method of nano-MgO preparation, and analyses the influence of Mg(OH)2 synthesized by the two methods on nano-MgO grain size and surface morphology, as well as the influence of different nano-MgO preparation methods on space charge, volume resistivity and DC breakdown field strength of the MgO/LDPE nanocomposites. The results show that the grain size of nano-MgO prepared by the traditional method is 22.74 nm, while that prepared by the microwave-assisted method is 12.76 nm. When the MgO content is 2wt%, it can effectively reduce the space charge accumulation in the composite materials, and improve the volume resistivity and DC breakdown field strength. |
