Polypyrrole-based emerging and futuristic hybrid nanocomposites

Enhancement of NO2 Gas Sensing Properties of Polypyrrole by Polarization Doping with DBS: Experimental and DFT Studies

“…These organic semiconductor sensors are characterized by the remarkable response signal, low energy consumption and excellent performance even with simple device configurations. − The perception of semiconductor gas sensor to gas molecules attributed to the adsorption of the gas molecules to the surface of sensitive material so depends on the change of carrier concentration arising from adsorbed gas molecules on the surface of the sensitive material …”

“…Doping and chemical modifications are often used to improve the carrier concentration and electronic conductivity. 26 Aromatic sulfonic acids are reported to improve the uniformity and integrity of coatings through π−π interactions between aromatic rings and pyrrole rings. 28 This can increase the internal potential and also the carrier concentration due to π−π interactions between aromatic rings and pyrrole rings.…”

“…The conductivity change is the most frequently used property in polypyrrole (PPy) based sensors to detect the carbon monoxide, carbon dioxide, nitrogen dioxide, hydrogen, and so on. Doping and chemical modifications are often used to improve the carrier concentration and electronic conductivity . Aromatic sulfonic acids are reported to improve the uniformity and integrity of coatings through π–π interactions between aromatic rings and pyrrole rings .…”
