Gas Sensors Based on Conducting Polymers

View Article: PubMed Central

ABSTRACT

The gas sensors fabricated by using conducting polymers such as polyaniline (PAni), polypyrrole (PPy) and poly (3,4-ethylenedioxythiophene) (PEDOT) as the active layers have been reviewed. This review discusses the sensing mechanism and configurations of the sensors. The factors that affect the performances of the gas sensors are also addressed. The disadvantages of the sensors and a brief prospect in this research field are discussed at the end of the review.

f12-sensors-07-00267: Configuration of a type of electrolytic cell for gas sensing.

Mentions: Amperometric method also has been applied for detecting gases. This sensor usually has a divided cell, with conducting polymer/metal/Nafion® as working electrode [173-175]. The supporting electrolyte usually is an inorganic acid to provide H+ ions for ionic conductance in Nafion® film. The configuration of the cell is presented in Figure 12.
