ABSTRACT
Polymer Nancomposites (PNCs) have come to be very useful for the advances of various sensors and biosensors. PNCs have a number of advantages as sensors, including high sensitivity, quick reaction time, room temperature functioning, and the ability to tune both chemical and physical properties by changing substituents. Due to the synergistic effect of the components, PNCs combine the advantages of polymers and other sensing materials such as carbonaceous materials, metal oxides, metals, and others, and their sensors display good sensing performance. This chapter describes mainly fabrication methods, working, types, importance and applications of these PNCs. Here we have discussed sensors based mainly on the composites of polyaniline, polypyrrole, and polythiophene. Finally, the prospects and development trends of conducting polymers and their nanocomposite-based sensors are discussed.
