Chemical Sensors Based on Conducting Polymers
Abo Akademi University, Process Chemistry Centre, Laboratory of Analytical Chemistry, Biskopsgatan 8, Turku FIN-20500, Finland
Conducting polymers such as polypyrrole (PPy), polythiophene (PT), polyaniline (PANI), and their derivatives, are truly multifunctional materials. The unique electrical, electrochemical and optical properties of conjugated polymers can be used to convert chemical information (concentration, activity, partial pressure) into electrical or optical signals in the solid state. Therefore, conjugated polymes are useful as transducers in chemical sensors. One of the key issues is to combine conjugated polymer transducers with selective molecular recognition in order to obtain durable chemical sensors.
