Purpose The purpose of this study is use to density functional theory (DFT) to investigate the molecular adsorption by PEDOT:PSS for different doping levels. DFT calculations are performed using the SIESTA code. In addition, the non-equilibrium Green’s function method is used within the TranSIESTA code to determine the quantum transport properties of molecular nanodevices. Design/methodology/approach Density functional theory (DFT) is used to investigate the molecular adsorption by PEDOT:PSS for different doping levels. DFT calculations are performed using the SIESTA code. In addition, the non-equilibrium Green’s function method is used within the TranSIESTA code to determine the quantum transport properties of molecular nanodevices. Findings Simulation results show very good sensitivity of Pd-doped PEDOT:PSS to ammonia, carbon dioxide and methane, so this structure cannot be used for simultaneous exposure to these gases. Silver-doped PEDOT:PSS structure provides a favorable sensitivity to ammonia in addition to exhibiting a better selectivity. If the experiment is repeated, the sensitivity is increased for a larger concentration of the applied gas. However, the sensitivity will decrease at a higher ratio than smaller concentrations of gas. Originality/value The advantages of the proposed sensor are its low-cost implementation and simple fabrication process compared to other sensors. Moreover, the proposed sensor exhibits appropriate sensitivity and repeatability at room temperature.

“…[21][22][23][24] In our previous work, we presented a simple and efficient sonochemical method capable of synthesizing ammonium vanadate nanofiber (AVNF: (NH 4 ) 2 V 6 0 16 •1.5H 2 O) to overcome the aforementioned problems. [25][26][27] The AVNFs were synthesized in 30 min using sonochemistry. The synthesis mechanism of this simple vanadate nanofiber is accompanied by a polyoxometalate reaction.…”

“…Conductive polymers, carbon nanomaterials, two-dimensional nanostructured materials, and their composites are utilized as sensing materials. The conductive conjugated polymer, poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT: PSS), has aroused increased interest in the field of gas sensing due to their flexibility and capability of sensing at room temperature. , Nevertheless, the gas sensors with pristine a PEDOT: PSS film suffer from limited response, tardiness response, and recovery characteristics . To overcome this issue, various PEDOT: PSS-based composites with polymers, metal oxide, and carbon nanostructure materials , have also been studied to improve the sensing performance due to a synergic or complementary effect.…”

Acetaldehyde (CH 3 CHO) is known as a primary carcinogen, and the development of wearable gas sensors for its detection at room temperature has rarely been rarely reported. Herein, MoS 2 quantum dots (MoS 2 QDs) have been employed to dope with poly(3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT: PSS) via a simple in situ polymerization technique, and the CH 3 CHO gas-sensing properties of the resultant flexible and transparent film were investigated. MoS 2 QDs had been evenly dispersed into the polymer, and it was shown that PEDOT: PSS doped with the 20 wt % MoS 2 QDs sensor exhibited the highest response value of 78.8% against 100 ppm CH 3 CHO and its detection limit reached 1 ppm. Moreover, the sensor response remained stable for more than 3 months. In particular, the different bending angles (from 60 to 240°) had little effect on the sensor response to CH 3 CHO. The possible reason for the enhanced sensing properties was attributed to the large number of reaction sites on the MoS 2 QDs and the direct charge transfer between the MoS 2 QDs and PEDOT: PSS. This work suggested a platform to inspire MoS 2 QDs-doping PEDOT: PSS materials as wearable gas sensors for highly sensitive chemoresistive sensors to detect CH 3 CHO at room temperature.
