Because of their good mechanical and processing properties as well as their low price, polymers have replaced such traditional materials as metal and wood in many fields of application. However, they lack one important characteristic-they do not conduct electricity. As with practically all organic substances known to date, they are usually good insulators; only a few categories can be classified as semiconductors. Materials which display higher conductivity can be obtained by synthesizing different polymers with a conjugated or aromatic backbone chain [1], but such materials, although classified as macromolecular, do not show the properties that would make polymers attractive from the point of view of application. Being poorly soluble, brittle, and melting at high temperatures, usually with decomposition, they are interesting practically only from the theoretical point of view.
