摘要

介电材料广泛应用于各种电气装置和设备，包括电容器、变压器、气体绝缘开关设备等；能量存储；电子封装；以及机械支撑[1], [2]。由于强电磁（电子注入或电离）或机械应力（接触电化），介电材料表面通常会存在表面电荷。一方面，表面电荷积累是一个关键因素，会极大地影响闪络，尤其是在高压直流设备中[3]。另一方面，高表面电荷密度也是储能或能量收集设备（如三电纳米发电机（TENG）、超级电容器等）所期望的[4]、[5]。由于表面电荷不易察觉，因此表面电荷表征技术在全面了解其特性方面发挥着重要作用。

Stories from China

Dielectric materials are widely used for various electrical devices and equipment, including capacitors, transformers, gas-insulated switchgear, and so on; energy storage; electronic packaging; and mechanical support [1], [2]. Surface charge commonly exists on the surface of dielectric material due to the strong electromagnetic (electron injection or ionization) or mechanical stress (contact electrification). On one hand, surface charge accumulation is a critical factor that can greatly influence the flashover, especially in high-voltage direct-current equipment [3]. On the other hand, high surface charge density is greatly expected for energy storage or harvesting devices, such as triboelectric nanogenerators (TENG), supercapacitors, and so on [4], [5]. Because surface charges are imperceptible, surface charge characterization techniques play an important role in comprehensively understanding their characteristics.

期刊介绍： The EI Magazine publishes articles written by authors from industry, research institutes and academia. The articles are more practical in content than the papers published in the Transactions. Usually three articles are published in each issue. The articles deal with dielectric materials, processes and new developments applied to industry products. Also the EI Magazine is used to promote upcoming conferences and solicits papers for the conferences. In addition, reports on past conferences are given in many issues. Book reviews and news items are included. An editorial is written by both the EIC and the President of DEIS in alternate issues. Advertising of insulation products appears in many issues.
