“…After PANI/PbI 2 formation, there is an obvious shift in the PANI peak located at 25.55°–26.05°, and the peak intensity increases from composite I to III. The shifts in the peak is related to the composite formation, the increasing in the intensity indicate high crystallinity of the formed composite 26,27 …”

The work reports on the preparation of polyaniline/lead iodide optoelectronic photodetector on antimony tin oxide (ATO) glass (PANI/PbI 2 /ATO) for providing a low-cost light sensor in the UV, Vis, and near IR regions (wide optical range photodetector).The deposition of PbI 2 nanoparticles was carried out on the surface of PANI using the ionic adsorption deposition method. Four ATO/PANI/PbI 2 composites (I, II, III, and IV) were produced by varying the Pb 2+ concentrations (0.01, 0.03, 0.05, and 0.07 M, respectively). The chemical structure, morphology, optical, and electrical properties were assessed using different analytical tools. Scanning electron microscopy (SEM) imaging revealed the formation of a nanoporous PANI network. After PbI 2 incorporation within the PANI network, white nanoparticles formed on the surface. The average size of the PbI 2 nanoparticles was 220, 270, 280, and 320 nm for Pb 2+ concentration of 0.01, 0.03, 0.05, and 0.07 M, respectively. Moreover, x-ray diffraction analysis confirmed PANI/PbI 2 composite formation, as witnessed by the appearance of new peaks at 12.77 , 34.31 , and 38.8 characteristic of PbI 2 .Through the optical analyses, the band gap values of the PANI/PbI 2 composites I, II, III, and IV were 2.63, 2.51, 2.46, and 2.48 eV, respectively. ATO/composite III was applied as an optoelectronic device for detection the light under different intensities or wavelengths, in which the current density (J ph ) increase from 2.5 to 3.42 mA cm À2 upon increasing of the light intensity from 25 to 100 mW.cm À2 , respectively. Moreover, the J ph recorded an optimum value of 3.33 mA cm À2 at 390 nm, which decreased to 2.09 mA cm À2 at 490 nm and increased again to 3.13 mA cm À2 at 636 nm. The optoelectronic photodetector exhibited an optimum incident photon to electron conversion efficiency (IPCE) of 10.7% at 390 nm. The photoresponsivity (R) and detectivity (D) were determined to be 107 mA cm À2 and 3.38 Â 10 10 Jones,

“…The reaction formula of organic carboxylic acid-doped PANI is shown in Figure 7(d). Liu 78 prepared water-soluble PANI by using a type of polymeric ionic liquid(PIL-Cl) as doping acid. PIL-Cl is a new type of imidazole-based dopant, which can provide protons and water-soluble groups for doping PANI to improve the solubility.…”

The application of polyaniline (PANI) in various fields is greatly limited by its poor solubility in water.Many methods which could elevate PANI water-soluble ability were used by researchers to expand its application range. In this paper, the research progress of the commonly used preparation methods of water-soluble PANI in recent years is reviewed. The main preparation methods of water-soluble PANI are categorized into four types including monomer modification, controlling the polymerization process, introducing water-soluble groups or substances, macromolecular reaction. They are composed of aniline derivative method, copolymerization, emulsion polymerization method, dispersion polymerization method, acid doping method, compound method, ATRP method. The principles of various methods to achieve water-solubility of PANI are introduced, the research on each preparation method reported before are introduced and their advantages and disadvantages are summarized.

“…This effect can be a consequence of chemical changes may be due to the high electrical field applied. Sharply increases in the UV zone have been associated with the transition between benzoid and quinoid structures in PANI, 34,40,41 shown in Figure 5, which could be promoted by an additional dehydrogenation because of the high electric field applied during the electrospinning. These changes are very subtle.…”

This work studies the hydrophilicity of electrospun microfibers of polyaniline (PANI) synthesized by plasma combined with polyethylene oxide (PEO). The hydrophilicity was evaluated measuring the contact angles of water, phosphate‐buffered saline (PBS) and Krebs‐Ringer (KR) biological solutions formed on the polymers. Plasma PANI is usually insoluble due to the crosslinking associated with the electrical discharges of the synthesis conditions; however, PANI was synthesized as semi‐soluble films, which were dissolved and mixed with soluble PEO to obtain PANI/PEO electrospun microfibers. Super‐hydrophilic (<30°) angles were obtained with water on PEO fibers and hydrophobic (>90°) angles were obtained with the PBS solution on PANI/PEO fibers. PANI films had contact angles, which increased with the salts of KR and PBS solutions, PEO films had sudden increments and reductions with the saline solutions. PANI showed the typical chemical groups of polyanilines and others as CN and CC associated with a high dehydrogenation, which disappeared in PANI fibers. Electromagnetic absorption peaks in the 270–320 nm wavelength range were detected in the fibers and not in the films, which can be associated with transitions between benzoid and quinoid PANI structures. These results indicated that PANI/PEO fibers would not dissolve as rapidly as PEO fibers in biological solutions.
