Abstract

Many nonconducting polymers are able to store a considerable amount of electrical charge for a long period of time. The stored charges may be real charges, polarization charges or both [1]. Permanently charged materials, which are called electrets, have been utilized in many technical applications such as electroacoustic transducers,radiation devices, electret filters or electrophotography [1]. Since these devices rely on the stability of the electrical properties of the polymers, an understanding of the mechanisms of charge storage and dipolar orientation is essential for their commercial success. It is the aim of this paper to provide a simple framework within for a discussion of electret properties,and to present selected examples showing how polymer structure impacts specific electrical properties such as charge storage, interfacial polarization and dipolar mobility.
