Conducting polymers (CP) are intrinsically conductive molecular solids built from polymeric conjugated molecules without covalent bounds between them. The molecular character of CP implies the translation of identical state from the bulk to the surface of the film without additional surface-induced defects. The absence of covalent bonds between backbones enables the access of external electrolyte to individual chain of CP forming the electrical double layer at the molecular scale.
