Abstract

The significant progresses of polymer-based nanocomposites with improved dielectric performances are urgently calling for an effect way to realise commercial production. Up to now, the biaxial stretching technology is still a powerful method to produce the high-performance dielectric films applied in the film capacitors due to its full-blown applications. In this work, a classical composite system of BaTiO3/polypropylene was applied to reveal the connection between the microstructure changes and dielectric properties of the corresponding nanocomposite films in the biaxial stretching process. The permittivity of BT-30 wt% nanocomposite reached 2.8 at 103 Hz after stretching, and its breakdown strength reached 340 MV/m. In addition, the breakdown strength of BT-10 wt% nanocomposite could even be promoted to 452 MV/m, which was 1.3 times higher than that before stretching. The microstructure test demonstrated that the rearrangement of nanofillers, high crystallinity and the oriented polypropylene crystals were advantageous to the improvement of breakdown strength for the stretched nanocomposite films. Therefore, the application of biaxial stretching technology into the preparation of nanocomposite dielectric film is an enormous potential way for the energy storage film capacitors.

基于双轴拉伸工艺的batio3 /聚丙烯纳米复合膜抗击穿强度的提高
提高介电性能的聚合物基纳米复合材料取得了重大进展,迫切需要找到一条有效的途径实现商业化生产。迄今为止,双轴拉伸技术由于其广泛的应用,仍然是制备薄膜电容器中高性能介质薄膜的有力方法。本文采用经典的BaTiO3/聚丙烯复合体系,揭示了双轴拉伸过程中纳米复合膜的微观结构变化与介电性能之间的关系。拉伸后,bt - 30wt %纳米复合材料的介电常数在103 Hz时达到2.8,击穿强度达到340 MV/m。此外,BT-10 wt%纳米复合材料的击穿强度甚至可以提高到452 MV/m,是拉伸前的1.3倍。微观结构测试表明,纳米填料的重排、高结晶度和聚丙烯取向晶体有利于拉伸后纳米复合膜击穿强度的提高。因此,将双轴拉伸技术应用于纳米复合介质薄膜的制备是一种潜力巨大的储能薄膜电容器。
