The recently discovered molecular mode of polarization, nomadic polarization, can provide giant electrical responses as it operates. It now remains to study the phenomenon thoroughly in various molecular realizations to see if it can provide materials with advantageous electrical properties. The evidence to date suggests that it does. Certain polymeric organic solids, containing extended domains of...
In the course of studying the properties of highly conjugated polymers we found that long range orbital delocalization conferred unexpected properties. The presence of giant electronic orbitals made these materials electroactive yet very stable. A new mode of electronic polarizability, a giant nomadic polarization resulted, [1-3] making these organic polymers among the most polarizable materials ever...
Many polymers, especially if linear, are amorphous as judged by macroscopic standards, but are locally rather ordered. They comprise a third class of what are generally termed “amorphous” solids. A comparison of the three classes of amorphous solids is shown in Table 1. If the polymers are highly aromatic in nature they can exhibit unusual electrical properties. They can range from being highly insulating...
In recent years, there have appeared a number of solids, some crystalline, some amorphous, in which the dielectric constants are strikingly high. Some are organic, some inorganic solids. Recently, a few have been found with dielectric constants from 50 to 300, 000. It is the purpose of this discussion to point out the types of pure homogenous solids which show such enhanced electrical polarizations,...
Conventional polymeric solids (pure, unfilled) have dielectric constants or relative permittivities, εr, in the range of about 1. 8 to 38. Recent years have seen a growing number of pure polymeric solids in which this value is exceeded. It is the purpose of this discussion to point out the types of homogeneous solids exhibiting such enhanced polarizations, and to suggest some of the reasons for it...
