Conducting polymers can conduct electricity and are synthesized from monomers like pyrrole and acetylene. Polyacetylene was the first discovered conducting polymer in 1977. Conducting polymers become conductive through a process called doping, where their backbone is chemically oxidized or reduced. This leads to the formation of charged solitons which allow charge carrier transport along the polymer backbone. Conducting polymers have applications in antistatic coatings, sensors, batteries, displays and biomedical devices due to their light weight, flexibility and low cost. However, issues remain around their reproducibility, stability, processability and short lifespan.
