This research focuses primarily on the uses of polymer electrets as an important class of organic materials finding their use in a variety of electronic and electrical engineering industries and ranging from photovoltaic cells to transducers, dosimeters, and other applications. This paper provides a broad summary about types of electrets and their mechanisms along with better knowledge of the electrical properties and detailed mechanisms involved in the buildup, transport, and storage of charges in organic polar polymers electrets. This work also aims to investigate the conditions favorable for obtaining long-lived electrets. This article highlights early research conducted in the field of electrets and reviews the current trends and applications of electrets in devices.
