Conductive polymers are a class of organic polymers that are capable of conducting electricity. These polymers are composed of organic molecules containing a large number of repeating structural units, which are connected to each other in a long chain-like structure. The repeating units are typically organic compounds containing carbon, hydrogen, oxygen, nitrogen, and sulfur. The electrical conductivity of these polymers is usually achieved by doping them with small amounts of metal ions such as lithium, sodium, or potassium. Conductive polymers have numerous potential applications, including use in solar cells, fuel cells, light-emitting diodes, sensors, and transistors.
