本文报道了一种用于测量电介质聚合物的相对介电常数和体积电阻率的高压测量装置。这些特性是在电场高达80 V µm−1和准静态频率低于1 Hz的情况下对薄膜进行评估的。结果发现，高场性能的FEP，PFA，聚酰亚胺和聚酯薄膜是可比的各自的低场值，而铁电PVDF极化行为变得明显，在高场。介电聚合物的高场特性在依赖于静电吸引的器件的设计中特别重要，例如在可调弯曲刚度结构中应用的电粘合层压板。
This paper reports on a high voltage measurement set-up for determining the relative permittivity and the volume resistivity of dielectric polymers. These properties were evaluated on thin films at electric fields up to 80 V µm−1 and in the quasi-static regime at frequencies lower than 1 Hz. It is found that the high field properties of FEP, PFA, polyimide and Mylar are comparable to the respective low field values, while for ferroelectric PVDF poling behavior becomes evident at high fields. High field properties of dielectric polymers are of particular importance in the design of devices relying on electrostatic attraction, such as electro-bonded laminates applied in tunable bending stiffness structures.
