Abstract

Metallised film capacitors consist of polymer dielectrics and electrodes which are considered as two layers. Due to the huge difference in thickness of two layers, metallisation can affect the microstructure and properties of metallised films, resulting in the bilayer structure model may not accurately describing properties. In this work, metallised films are considered as a whole rather than two layers of dielectric and electrode, whereas the process of film metallisation is regarded as a surface modification of the dielectric film. Metallised films with different metal layer thicknesses are prepared by vacuum evaporation. We investigated the dielectric, electrical and self-healing properties of metallised films. Films with thicker electrode present higher dielectric constant, conductivity, energy density and lower breakdown strength. Thinner metal layers result in less self-healing energy and better self-healing property. The difference in properties is attributed to the surface modification of dielectric films by nanoscale metallisation. Thicker electrode contributes to smaller surface roughness, which increases the polarization and charge capacity of metallised films, but also implies worse self-healing property. Surface modification provides a new perspective for researching metallised films.

介电薄膜金属化过程中的表面修饰效应
金属化薄膜电容器由聚合物电介质和电极组成,电极被认为是两层。由于两层厚度的巨大差异,金属化会影响金属化膜的微观结构和性能,导致双层结构模型可能无法准确描述性能。在这项工作中,金属化薄膜被视为一个整体,而不是两层电介质和电极,而薄膜金属化的过程被视为电介质薄膜的表面改性。采用真空蒸发法制备了不同金属层厚度的金属化薄膜。我们研究了金属化薄膜的介电、电学和自愈性能。电极越厚,膜的介电常数、电导率、能量密度越高,击穿强度越低。金属层越薄,自愈能量越少,自愈性能越好。这种性能的差异是由于介质薄膜的纳米级金属化表面改性所致。电极越厚,表面粗糙度越小,金属化膜的极化能力和电荷容量越大,但自愈性越差。表面改性为金属化薄膜的研究提供了新的视角。
