This work discusses sensing performance dependence of PEDOT polymer and its composites on the counter ions used in the polymerization process. The sensors based on PEDOT-RGO composite show reversible response to NO2, while on PEDOT/LiClO4 irreversible. As a result, PEDOT-RGO could be used as a typical gas sensor, while sensor based PEDOT/LiClO4 could be used as an integrating gas sensor, also known as an accumulating gas sensor. The irreversible nature of the response occurs also in the case of polypyrrole/LiClO4. The nature of PPy response to toxic gases does not allow using the sensor in conventional way. However, the information about the concentration could be acquired from the response using a linear approximation, a non-linear approximation and a tangent method.
