Conducting polymers (CPs) are organic materials that exhibit electrical and optical properties like metals and semiconductors. They combine the flexibility of traditional polymers with the ability to conduct electricity, making them ideal for applications in electronics, sensors, energy storage, and biomedical devices. The discovery of CPs dates back to 1862, with significant advancements in the 1960s and 1970s, including developing materials like polyacetylene and poly(sulphur nitride). The conductivity of CPs is primarily determined by doping processes involving the introduction of charge carriers, such as solitons and polarons. CPs offer various advantages, such as chemical tunability, lightweight nature, and corrosion resistance. However, their performance continues to evolve, showing significant potential to rival metals and semiconductors. CPs are often combined with carbon nanomaterials like graphene to enhance their properties. However, their conjugated backbone structure makes them insoluble, limiting their processability. Efforts to improve solubility, such as adding flexible side chains and using polar or nonpolar solvents, have been explored. Tailoring CPs through chemical modifications, copolymerization, and functionalization is key to enhancing their conductivity, flexibility, and chemical stability. This has expanded their applications in flexible electronics, organic photovoltaics, biosensors, and drug delivery systems. Characterization techniques such as FTIR, XRD, and AFM are crucial for assessing their properties. However, challenges like scalability, maintaining conductivity while enhancing flexibility and addressing environmental concerns remain. The ongoing development of CPs through innovative design approaches holds significant promise for next-generation technologies. Hence, tailored CPs offer vast potential, addressing current limitations and enabling advancements in various industries.
