Abstract

Today nanotechnology has created a new dimension to enhance the properties of existing conventional insulating material. Polymer nano-composites belong to such type of material which shows improved insulation properties and dielectric behavior in high voltage engineering application due to their unique properties and compact size of insulation. Recently, the research focuses on determining the characteristics of various polymer-filler combination to obtain better insulation material with excellent electrical properties. In our work we focused mainly on the preparation of epoxy (Bisphenol-A) based nano-composites with different insulating fillers like TiO2, Al2O3 and ZnO of very low concentration (0.1-1.5%), small thickness (100-500 microns) and homogeneous distribution of fillers. Breakdown tests were conducted on these nano-composite samples and their breakdown strengths are determined. The results showed that the breakdown voltage is found to vary for different nano-composites based on the properties of nanofillers. And it is influenced by the type of the fillers and the different nano-composites show improved electrical behavior at critical concentration of filler.

填料浓度对聚合物纳米复合材料击穿的影响

今天，纳米技术已经创造了一个新的维度，以提高现有的传统绝缘材料的性能。聚合物纳米复合材料由于其独特的性能和紧凑的绝缘尺寸，在高压工程应用中表现出良好的绝缘性能和介电性能。近年来，研究的重点是确定各种聚合物-填料组合的特性，以获得具有优异电性能的绝缘材料。在我们的工作中，我们主要研究了用不同的绝缘填料如TiO2、Al2O3和ZnO制备低浓度(0.1-1.5%)、小厚度(100-500微米)和填料分布均匀的环氧(双酚a)基纳米复合材料。对这些纳米复合材料进行了击穿试验，测定了其击穿强度。结果表明，基于纳米填料的特性，不同纳米复合材料的击穿电压不同。在填充剂的临界浓度下，不同的纳米复合材料的电学性能有所改善。
