In this article, the results of the process and fabrication of ammonia gas sensors are obtained through the production of poly(vinyl alcohol) and polyaniline (PVA/PANI) nanofibers in different concentrations deposited on interdigitated electrodes (IDEs) The results showed good interaction between PVA and PANI, as well as the solvents involved, with good adhesion of the nanofibers in substrate, shown for morphological analysis by scanning electron microscopy (SEM). The good performance of the gas sensor was carried out by direct current measurements. It has been proven that the high surface density, dimensions, and quality of nanofibers are essential parameters for a good response of the ammonia gas sensor. © 2018 Wiley Periodicals, Inc. J. Appl.

“…In addition, the PANI and the modified copolymer was a low-cost raw material with the property of forming film conveniently, and a kind of high conductive polymer material with excellent comprehensive properties [1][2][3][4][5].Due to nickel fiber has good corrosion resistance and magnetic, it was widely used in the field of shielding materials and absorbing materials. Similar to the metal fiber, nickel fiber with large length diameter ratio and make it easier to form bridging structures in conductive composite [6][7][8][9]. Conductivity of poly aniline will get better when the proton acid used as a dopant, the conductive properties of PANI coating layer prepared by different doping agents were different.…”

In order to improve the conductivity of the nickel fiber, polyaniline (PANI) of synthesis by chemical oxidative polymerization was coated. The influences of dopant type and content, reaction time, reaction temperature and stirring rate on the conductivity of the PANI coated nickel fiber were investigated. SEM and NMR were used to characterize morphology of products. The conductive of the PANI coated nickel fiber was tested by four-point probe conductivity tester. The results showed that the PANI coated layer was uniform and stabilized when the p-toluene sulfonic acid (PTS) used as dopant, the PANI coated nickel fiber has the highest conductivity of 5×10-5 s∙cm−1when was coated at parameters of the C (PTS) of 0.1 mol/L, the reaction time of 5 hours, the reaction temperature of 5 °C, as well as the stirring rate of 60 r/min.

Résumé La polyaniline (PANI) est un polymère organique qui présente une grande stabilité environnementale et une grande conductivité électrique. L’évolution de ces deux propriétés en fonction du temps a été réalisée sur des échantillons vieillis dans des solutions fortement acides (H2SO4) à différentes températures. Des prélèvements réguliers d’échantillons sont caractérisés par FTIR, UV, AFM et MEB. La conductivité sera suivie par la méthode des 4 pointes et la stabilité thermique de la PANI par DSC, ATD‐ATG. Ces stabilités thermiques et électriques représentent un verrou technologique pour de nombreuses applications possibles des PANI en milieu agressif. Afin de maîtriser le matériau polymère conducteur, il est nécessaire d'avoir avant une bonne compréhension des paramètres qui gouvernent les mécanismes de transport. Ces paramètres dépendent directement du mode d'élaboration qui est optimisé.
