Intrinsically conductive polymers (ICPs) are organic polymers with a conjugated system of single and double covalent bonds in their backbone. Process of doping the polymer chain introduces charge carriers, so-called solitons, polarons and bipolarons. This makes ICPs in doped state electrically conductive. In addition to high electrical conductivity in the doped state, ICPs exhibit also good capacitive, optical, and physical (e.g. flexibility) properties. To improve their stability, which is the main limitation of their use, nanocomposite ICP materials are usually prepared. ICPs are used in anti-corrosion coatings, sensors and shielding against electromagnetic radiation. They also play an important role in medicine, energy storage devices and advanced technology.
