Abstract
A giant type of polarization appears in certain highly aromatized polymeric solids. It arises when (a) the structure can inherently dissociate to form electronic carriers, and (b) when there are long domains of equivalent sites for freed electroonic carriers to rove about in response to an external electric field. It is referred to as ´nomadic´ polarization, and joins the familiar electronic, atomic, and dipolar orientation types as a fourth molecular mode of polarization. Applications for the new super-dielectrics based upon these concepts will be many; including improved capacitor materials for better energy storage and control, low visibility coatings, obscuration, and EMP shielding, while in microcircuitry applications are transducers and parametric circuits. Progress in this promising new field is reviewed. A discussion of structures essential for nomadic polarization is given, together with some new results exemplifying these concepts. Future work and trends are suggested.
