N2 - Conductive polymers have demonstrated tremendous promise for room temperature gas sensing due to the rapid redox reaction mechanism. However, low sensitivity, poor stability, and gas selectivity, due to their comparatively low conductivity and high affinity toward water molecules and volatile organic chemicals, prevent them from being used in real gas sensor applications. Highly effective gas sensors have been developed using polymer-metal oxide composite materials because metal oxides have long been recognized as the perfect choice for gas detection. This chapter briefly overviews the characteristics of conductive polymers and several polymerization processes used to synthesize polymers and composites of polymers and metal oxides. This chapter also discusses the efficacy of pure conductive polymer-based gas sensors and the necessity of polymer-metal oxide composites. In addition, many combinations of metal oxides and conductive polymers utilized for gas-sensing applications have been described in detail with a variety of affecting parameters such as noble metal inclusion, morphological tuning, heterojunction creation, and so on.
