An exciting new category of polymer solids, polymer electrets, has been the subject of intense research and development activities during the past eight years. The primary properties possessed by these materials are piezoelectricity and pyroelectricity, and the kinds of devices that can exploit these properties include microphones and heat detectors. Polymer electrets also can serve as radiation dosimeters or imaging devices. In addition, devices which can exploit the ferroelectric behavior of certain polymer electrets can be designed to store information which is in the form of electrical signals. Some of the polymers used in these applications are commonly available solids, such as polyvinylchloride, polymethylmethacrylate, and especially polyvinylidene fluoride. This paper is concerned with the mechanism of persistent electrical polarization in polyacrylonitrile. Results of experiments are presented in curves, which are analyzed.
