Introduction Polymers were considered to be electrical insulators before the invention of conducting polymers (conjugate polymers), but these organic polymers have unique electrical and optical properties similar to those of inorganic semiconductors. 1 A conjugated carbon chain consists of alternating single and double bonds, where the highly … WebPolymers as a replacement for metal. Metals are replaced by polymers more and more often. In addition to the high chemical resistance, above-all the low density of the polymers is primarily a huge advantage with regard to saving weight. However, the rigidity of the materials must stand up to the challenges of the application.
