“…As can be observed, the addition of PANI to Ce-doped ZnO improved the produced nanocomposites dielectric constant and dielectric losses and there is decrease in both the values with increasing dopant concentration. Considering the above results, it has been hypothesized that the increased dielectric constants and losses may result from the metal oxide's increased conductivity following the incorporation of PANI, caused by an increase in the inorganic nanoparticles' dispersion on the PANI matrix in the synthesized nanocomposites [56,57]. The PANI@Ce-doped ZnO nanocomposites higher dielectric constant and losses suggests that it may store electric potential energy more effectively when subjected to various electric fields and higher value of dielectric losses nanocomposite indicates a higher level of energy dissipation within the material when subjected to an alternating electric field.…”

To address the significant issue of wastewater treatment, this research focused on synthesizing PANI@Ce-doped ZnO (PCZ), a ternary heterojunction with varying dopant concentrations. This heterojunction was prepared using an ultrasonic-assisted wet impregnation technique and underwent comprehensive analysis through several techniques, including XRD, UV-DRS, Photoluminescence, FE-SEM, EDAX, FTIR, and Impedance Analyzer. The synergy between the organic and inorganic frameworks resulted in an additive effect on the photocatalyst's degradation efficiency. This was achieved by enhancing its light-absorption properties and tuning the band gap energy. In the photocatalytic degradation process, reactive oxygen species (ROSs), including O2, OH, and h+, played a crucial role in breaking down MB (Methylene Blue) using the PANI@Ce-doped ZnO nanocomposites. Comparing PANI@Ce-doped ZnO with a 1% Cerium concentration (PCZ1) to its counterparts with different dopant concentrations, PCZ1 exhibited significantly elevated photocatalytic activity. This enhancement can be attributed to the improved transfer and separation of photogenerated charge carriers, which resulted from the effective formation of a heterojunction between the two components with a large trapping site.

“…A dopant is typically introduced during the synthesis of CPs, to produce favourable electrical characteristics. Dimethyl sulfoxide (DMSO), ethylene glycol (EG), sulfuric acid (H 2 SO 4 ), phytic acid, and p -Toluenesulfonic acid ( p TSA) are commonly employed as dopants [ 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. In their research of crosslinked porous 3D hydrogel–PEDOT CP scaffolds, Mawad et al (2016) mixed all of the required chemicals, followed by a filtration process [ 55 ].…”

“…Unfortunately, electroactive aniline-based oligomers are toxic to human bodies. In response to this observation, Mawad et al (2016) proposed 3,4-ethylene dioxythiophene (EDOT)-based oligomers as an alternative to replace aniline-based oligomers, to minimise the biomaterial’s toxicity [ 54 ].…”

Scaffolds support and promote the formation of new functional tissues through cellular interactions with living cells. Various types of scaffolds have found their way into biomedical science, particularly in tissue engineering. Scaffolds with a superior tissue regenerative capacity must be biocompatible and biodegradable, and must possess excellent functionality and bioactivity. The different polymers that are used in fabricating scaffolds can influence these parameters. Polysaccharide-based polymers, such as collagen and chitosan, exhibit exceptional biocompatibility and biodegradability, while the degradability of synthetic polymers can be improved using chemical modifications. However, these modifications require multiple steps of chemical reactions to be carried out, which could potentially compromise the end product’s biosafety. At present, conducting polymers, such as poly(3,4-ethylenedioxythiophene) poly(4-styrenesulfonate) (PEDOT: PSS), polyaniline, and polypyrrole, are often incorporated into matrix scaffolds to produce electrically conductive scaffold composites. However, this will reduce the biodegradability rate of scaffolds and, therefore, agitate their biocompatibility. This article discusses the current trends in fabricating electrically conductive scaffolds, and provides some insight regarding how their immunogenicity performance can be interlinked with their physical and biodegradability properties.

“…There is probably no one who does not know the importance of conductive polymers in the field of materials, energy, technological and innovative medical science in our age and that they are open to development in every field (Shi et al2015;Baughman et al 1996). Conductive polymers have become materials that have the feature of a remedy, sometimes in the field where energy efficiency is needed, sometimes in the application area, where the materials used should be cheaper, flexible, lighter and more economical (Omar et al 2019;Grancaric et al 2018;Margolis et al 2012) Especially alternative to inorganic materials, less waste, more environmentally friendly and recyclable polymers continue to attract the attention of scientists with all their features (Phan et al 2019). It is very crucial to optimize and modify the optical and electronic properties of conjugated polymers and to modify the chemical structure of the material as a conductive polymer engineer.…”

This study is about the electrochemical polymerization of the monomer of carbazole, whose anodic polymerization is very common in the literature. When the studies in the literature were examined, it was seen that the electrochromic properties of carbazole were not examined. For this purpose, electrochemical and optical properties were investigated in detail by polymerizing carbazole on both glassy carbon and ITO glass electrodes in 0.1 M TABPF6/ DCM medium using the cyclic voltammetry method. The polymer film synthesized by electroanalytical methods showed reversible electrochemical oxidation process properties as well as electrochromic properties. The polymer film synthesized by electroanalytical methods showed reversible electrochemical oxidation process properties as well as electrochromic properties. Considering that this study will form a basis for other studies, it is thought that the evaluation of carbazole monomer in terms of its electrochromic properties will provide a great deal to the literature.
