摘要： 电容器自愈是一个通用术语，用于描述在电气击穿后恢复介质电容器功能的物理和化学过程。 自愈的效果取决于金属化薄膜电容器的元素组成。 我们从化学角度报告了自愈的原子模拟，证明了通过寻找各种聚合物和电极之间的相互作用来调节烟尘的电导率是不可能的。 所有研究的烟尘样品都显示出富含碳的半导体骨架，具有大量不饱和的C-C共价键。 它们表现出相同数量级的电导率，无论所选绝缘聚合物的初始化学组成和性质如何。 在报告新结果时，我们讨论了减少烟尘电导率的不太明显的方法。 我们得出结论，电容器自愈的质量可以通过计算电气击穿的气态副产物或评估固态半导体对应物的体积来评估。 显示英文摘要

摘要： Capacitor self-healing is a generalized term to describe physical and chemical processes restoring the functionalities of a dielectric capacitor after an electrical breakdown. The efficacy of self-healing depends on the elemental composition of a metalized-film capacitor. We report atomistic simulations of self-healing from a chemical perspective proving the impossibility of tuning the electrical conductivity of the soot by finding an interplay of various polymers and electrodes. All investigated soot samples turn out to possess carbon-rich semiconducting skeletons with numerous unsaturated C-C covalent bonds. They exhibit electrical conductivities of the same order of magnitude, irrespective of initial chemical compositions and properties of the chosen insulating polymers. Upon reporting the new results, we discuss less evident approaches to diminish the soot conductivity. We conclude that the quality of capacitor self-healing can be assessed by counting gaseous by-products of electrical breakdown or evaluating the volume of the solid-state semiconducting counterpart.
