为了制备以聚甲基丙烯酸甲酯(PMMA)填充纳米孔的新型一维纳米材料并对其电性能进行研究,采用偶氮二异丁氰引发甲基丙烯酸甲酯(MMA)在一种径迹刻蚀聚合物纳米孔膜的纳米孔(孔径为50nm)中聚合,制得此一维纳米材料,并通过高压设备、介电谱仪、高阻计等装置测定此一维纳米材料的击穿电压、电导电流、相对介电常数和介质损耗角正切随频率变化情况等介电性能。实验结果表明这种新型一维纳米材料的击穿场强虽然低于PMMA,但较原始聚合物纳米孔膜的击穿场强有所提高,且通过控制反应条件等,具有进一步提高的可能。
In order to prepare a novel one-dimensional nanomaterial filled with polymethylmethacrylate (PMMA) and study its electrical properties, MMA was initiated with azobisisobutyronitrile The one-dimensional nanomaterials were prepared by polymerization of nanopores (pore size: 50 nm) of the etched polymer nanoporous membrane, and the breakdown of the one-dimensional nanomaterials was measured by means of high-voltage equipment, dielectric spectroscopy, Voltage, conductance current, relative permittivity and dielectric loss tangent with frequency change and other dielectric properties. Experimental results show that although the breakdown field strength of the novel one-dimensional nanomaterials is lower than that of PMMA, the breakdown field strength of the nano-porous nano-film is improved, and the further improvement is possible by controlling the reaction conditions.
