无机驻极体比有机驻极体因其寿命长,耐高温以及可以制成异型、微型、集成化器件而倍受关注。但对无机驻极体材料与应用开发的系统基础研究工作尚未形成应有规模。本文根据注极电荷的储存、输运机制与应用开发的要求,提出对材料组分、结构、制备工艺等需要研究解决的若干基本问题。 Inorganic electret organic electret because of its long life, high temperature and can be made of special-shaped, miniature, integrated device and much attention. However, the basic research work on inorganic electret material and application development has not yet been formed yet. According to the requirements of storage, transport mechanism and application development of the polar charge, some basic problems need to be studied and solved, such as material composition, structure and preparation technology.
