Notes:
Mobile ions can be introduced thereby increasing the conductivity, with a limiting operating temperature range of 200°-250°C. Conductivity can be increased with the formation of conjugatd double bonds. Polymeric compounds may be synthesized with metallocyclic groups, where an atom of metal is bound to nitrogen atoms in a heterocyclic system in the basic chain of conjugation of the macromolecule. Here phtalocyanimes possess the greatest thermal stability. Lastly there are semiconducting polymers with conjugated double bonds containing hetero-atoms in the principle chain, having unpaired electrons of oxygen and nitrogen.
