In this work, we report the fabrication of sensors’ element for humidity or gases, prepared by in situ polymerization of aniline N‐propansulfonic acid using ammonium persulfate in acidic medium. The polymer is being used in the form of powder or deposited in multiple layers onto the PET film. Various techniques including Fourier Transform infrared (FTIR), ultraviolet‐–visible spectroscopy (UV–vis), X‐ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize the as‐prepared sensing materials. The film has been tested for humidity influence, where the significant variations in electrical characteristics were observed, suggesting its usefulness for humidity sensors. Also, for different organic and inorganic gases, a relatively low operating temperature and important sensitivity were observed that indicate its applicability as an active element for general gases sensors. © 2019 Wiley Periodicals, Inc.

“…Colloidal dispersions allow for the solution processability and easy deposition by means of low cost of spin coating or printing techniques. 22,23 PANI is used in variety of applications 18 that exploit salt-base transition, electrochemical switching and optical, adsorption and catalytic ability, biocompatibility, 24 and many other features. Owing to the diverse palette of applications that further use electrical properties of PANI, such as energy conversion and storage, 25 it is crucial to study in detail the influence of charge transport and its dependence on different operating temperatures to understand the electrical properties of this material, to fully exploit PANI in niche electronic applications.…”

ABSTRACT:The charge transport properties of thin films prepared from colloidal dispersion of polyaniline stabilized by poly(N-vinylpyrrolidone) (PANI/PVP) have been investigated. The electrical characterization of coplanar device comprising of gold electrodes and PANI/PVP film deposited by spin coating served to gain insights into the contact and bulk resistance. The films prepared from PANI/PVP colloidal dispersion show high stability over a large temperature range. Temperature dependent measurements in the range from 90 to 350 K reveal that the charge transport can be described by a threedimensional variable-range hopping mechanism as the dominant mode in the films. The stability of the films cast from dispersion within a large temperature range opens the possibility of the application as a polymer semiconductor layer in sensors and charge-transport interlayer in organic solar cells.

Electrochemical impedance spectroscopy (EIS), one of the techniques for electrochemical analysis, has been used for a wide range of applications especially chemical‐ and bio‐sensing. Besides, EIS is one of the few techniques that has been proven useful for membrane fouling detection. Electrodes are some of the most essential components for analytes detection applications with EIS. With the advances in printing technology, the fabrication of advanced printed electrode systems with miniature designs and improved sensitivity for electrochemical sensing is made possible. This review addresses recent advances in printed electrodes for electrochemical impedance spectroscopy with the emphasis placed on discussing the use of printed electrodes for membrane fouling detection. Common electrode designs and materials for electrochemical impedance spectroscopy are discussed, along with practical examples of these printed electrodes. The commonly used printing techniques for the fabrication of printed electrodes are also deliberated. The successful realization of printed electrodes for EIS requires careful design of electrodes, proper selection of electrode materials, as well as optimization of the printing process. It is expected that printed electrodes will be widely accepted for EIS sensing applications and will facilitate the creation of low‐cost high‐performance sensing devices.
