Flexible and highly sensitive polyaniline-based (PAni) ammonia (NH 3 ) gas sensors were developed through an in-situ chemical oxidative polymerization process of aniline on a polyethylene terephthalate substrate at three different temperatures viz. 35⁰C, 0⁰C and -5⁰C. In the beginning stage, they were characterized with respect to their structural, morphological, and compositional analysis studies and in second stage, selectivity was tested for oxidizing (nitrogen dioxide, NO 2 ) and reducing (NH 3 , ethanol, methanol and hydrogen sulphide, H 2 S) gases. The sensor fabricated at 0 o C showed optimum response of 26% to 100 ppm NH 3 gas which was superior to those obtained for 10 sensors developed at 35⁰C (19%) and -5⁰C (23%). As-developed low-temperature flexible gas sensor has demonstrated fast response (19 s) as well as recovery times (36 s), 99 % reproducibility and good stability, enabling potential of commercial application, for example in industry where high temperature operation is prohibited. The impedance spectroscopy was used to investigate the plausible interaction mechanism of NH 3 gas molecules with flexible PAni film. Operation of NH 3 gas sensor, fabricated on a laboratory scale was tested and explored as a demo-video clip; available online as EIS. 15 45

Electrochromism is a unique phenomenon based on the ability to change the optical properties or color of a material when an external potential is applied. Conventional electrochromic materials are based on inorganic materials. In particular, transition metal oxides, such as tungsten oxide and molybdenum oxide, are extensively investigated for use in commercial electrochromic devices (ECDs). However, these devices have several drawbacks including single color change, expensive materials, and a slow switching speed. To overcome these challenges, new substitute materials need to be investigated with the advantages of multicolor, fast response, low cost, ease of processing, and environmentally friendly materials. Among the many great candidates, conducting polymers (CPs) have emerged as a prominent approach. In this review, the current state‐of‐the‐art development of ECDs based on the three most popular CPs, namely, polyaniline, polypyrrole, and poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate, is introduced, with emphasis on their synthetic approaches and electrochromic performance.

“…It was found that 85 to 90% of the initial capacity was recovered whatever the electrolyte [31,38]. The CME was shown to be a convenient technique for studying the effects of the synthesis temperature on electrical properties of polyaniline and their electrochemical characteristics in a silver CME [129] or to synthesize and characterize Hgpolyaniline composite powder material [80] and Ag nanoparticles polyaniline powder material [107].…”

International audienceThe cavity microelectrodes (CMEs) have been introduced in the 1990s and since then have been employed for the characterization of various types of materials ranging from materials used for energy storage, biological applications, catalysis characterization, or corrosion studies. This technique takes advantage of working on small amount of pure electroactive materials (few hundreds nanograms) using usual electrochemical techniques (cyclic voltammetry, electrochemical impedance spectroscopy, etc.) and allows a rapid screening of the electrochemical behavior of new materials. The CME development and its main applications for the electrochemistry of powder materials are reviewed and discussed
