“…Among the various CPs, such as polyaniline (PANI), Polyfuran (PFu), polypyrrole (PPy) and polythiophenes (PTs), poly(3,4-ethylene-dioxythiophene) (PEDOT) has already found application in different fields [ 20 ], due to its high chemical stability and conductivity. Several researchers have demonstrated that the incorporation of PEDOT into Polyacrylamide (PAM) [ 21 ], Polyethylene terephthalate (PET) [ 22 ] or Polyvinyl alcohol (PVA) [ 23 ] matrices allows for the production of conductive materials suitable for the detection of nitrogen dioxide [ 24 ], ammonia [ 25 ], acetone, ethanol, methanol and tetrahydrofuran vapors at room temperature [ 26 ]. From this perspective, the coupling of PEDOT with a 3D printable polymer can be considered a reliable manufacturing strategy for producing cumulative adsorption materials with customized architectures.…”

We report on the preparation and stereolithographic 3D printing of a resin based on the composite between a poly(ethylene glycol) diacrylate (PEGDA) host matrix and a poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) filler, and the related cumulative volatile organic compounds’ (VOCs) adsorbent properties. The control of all the steps for resin preparation and printing through morphological (SEM), structural (Raman spectroscopy) and functional (I/V measurements) characterizations allowed us to obtain conductive 3D objects of complex and reproducible geometry. These systems can interact with chemical vapors in the long term by providing a consistent and detectable variation of their structural and conductive characteristics. The materials and the manufacture protocol here reported thus propose an innovative and versatile technology for VOCs monitoring systems based on cumulative adsorption effects.

“…PEDOT:PSS is a widely used conjugated polymer due to its excellent electrical conductivity, high transparency, good processability, and low redox potential [ 123 , 124 ]. Firstly, PEDOT:PSS was dissolved in the mixture of dimethyl sulfoxide (DMSO), ethylene glycol (EG) and triton x-100 to prepare the graphene–PEDOT:PSS ink, and then stirred at room temperature.…”

The use of graphene and its derivatives with excellent characteristics such as good electrical and mechanical properties and large specific surface area has gained the attention of researchers. Recently, novel nanocomposite materials based on graphene and conducting polymers including polyaniline (PANi), polypyrrole (PPy), poly (3,4 ethyldioxythiophene) (PEDOT), polythiophene (PTh), and their derivatives have been widely used as active materials in gas sensing due to their unique electrical conductivity, redox property, and good operation at room temperature. Mixing these two materials exhibited better sensing performance compared to pure graphene and conductive polymers. This may be attributed to the large specific surface area of the nanocomposites, and also the synergistic effect between graphene and conducting polymers. A variety of graphene and conducting polymer nanocomposite preparation methods such as in situ polymerization, electropolymerization, solution mixing, self-assembly approach, etc. have been reported and utilization of these nanocomposites as sensing materials has been proven effective in improving the performance of gas sensors. Review of the recent research efforts and developments in the fabrication and application of graphene and conducting polymer nanocomposites for gas sensing is the aim of this review paper.

This paper presents an approach for design and realization of a smart device for measuring and monitoring ammonia concentration. The developed system included two parts: hardware and software, in which the hardware of the system has been developed based on the ATMEGA328P microcontroller in order to collect data from the ammonia sensor MQ135. Meanwhile, the software is developed for signal processing and warning according to different thresholds. Collected data by the system is then transmitted to a computer via the wireless communication protocol. In addition, an interface is also designed on computers to collect and monitor data from sensors. The developed system allows to measure ammonia concentration up to 300ppm and has been tested not only at the laboratory but also at NPK factory of Lamthao Fertilizers and Chemicals Joint Stock Company. Experimental results show the desired performances of the developed system.
