“…Recently, hybrid EC materials incorporating inorganic solids into electroactive polymers have been rapidly developed, especially for metal oxides such as titanium(IV) oxide (TiO 2 ), zirconium(IV) oxide (ZrO 2 ), and WO 3 . Additionally, conductive nanomaterials such as carbon nanotubes, graphene, gold, and silver nanowires are good candidates for EC hybrid materials …”

In this research, a new design of organic‐inorganic hybrid networks involving covalently bonding, novel, electron‐donating triphenylamine (TPA)‐containing electroactive molecules to inorganic metal oxides is successfully developed by using a facile sol‐gel process. These anodically electrochromic TPA‐containing materials exhibit multicolor electrochromic behaviors at various oxidation states. By introducing zirconium oxide into electrochromic materials, not only can an excellent optical transparency in the visible light region at a neutral state be achieved given the nature of the large energy bandgap, but the electrochromic switching can also be driven by a lower oxidation potential with an enhanced response capability (shorter coloring times and bleaching times). Moreover, the hybrid films show outstanding electrochemical stability and high reversibility under long‐term operations owing to their good adhesion to the electrode. Consequently, the electrochromic devices derived from these novel hybrid electroactive materials reveal a huge potential for electrochromic applications.

“…The PSS, a vinyl polymer having sulfonate (−SO 3 − ) groups promotes para-directed polymerization of aniline, which resulted in the formation of PANI with lower structural defects . A water-soluble PANI:PSS was proposed as an alternative to substitute PEDOT:PSS with high cost and poor redox behaviors [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. The synthesis of PANI:PSS NPs was proposed by simple chemical oxidative polymerization of aniline in the presence of the PSS (Figure 8) [24][25][26][27][28].…”

“…Furthermore, the −SO 3 − groups of PANI:PSS enable electrostatic interactions with various materials, such as carbons, inorganics, and polymers [20][21][22][30][31][32][33][34][35][36][37]. Therefore, various PANI:PSS-based composites were designed for SCs [23,[25][26][27], ECs [28][29][30], supercapacitors [31][32][33][34], sensors [22,24,35,36], antennas [37], and so forth. It was obvious that the PANI:PSS can act as an efficient hole transport layer (HTL) material in perovskite solar cells (PSCs) and organic solar cells (OSCs) [23,25,26].…”

Solution-processable conducting polymers (CPs) are an effective means for producing thin-film electrodes with tunable thickness, and excellent electrical, electrochemical, and optical properties. Especially, solution-processable polyaniline (PANI) composites have drawn a great deal of interest due to of their ease of film-forming, high conductivity up to 103 S/cm, excellent redox behaviors, processability, and scalability. In this review, basic principles, fabrication methods, and applications of solution-processable PANI composites will be discussed. In addition, recent researches on the PANI-based electrodes for solar cells (SCs), electrochromic (EC) windows, thermoelectric (TE) materials, supercapacitors, sensors, antennas, electromagnetic interference (EMI) shielding, organic field-effect transistors (OFETs), and anti-corrosion coatings will be discussed. The presented examples in this review will offer new insights in the design and fabrication of high-performance electrodes from the PANI composite solutions for the development of thin-film electrodes for state-of-art applications.

“…Such a nanocomposite of PEDOT/poly(styrene sulfonate) with 3.2 nm AuNPs or 6.5 nm AgNPs possessed modified colors in colored/bleached states [13]. The incorporation of AuNPs into the structure of PANI copolymerized with p-aminothiophenol in the presence of poly(styrene sulfonate) (PSS) was performed by Xiong et al [17]. Such nanohybrids possessed improved electrochemical activity and shorter switching time.…”

Conjugated polymers (CPs) are attractive materials for use in different areas; nevertheless, the enhancement of electrochromic stability and switching time is still necessary to expand the commercialization of electrochromic devices. To our best knowledge, this is the first study demonstrating the employment of electrodeposited gold nanostructures (AuNS) for the enhancement of CPs’ electrochromic properties when a transparent electrode is used as a substrate. Polyaniline–poly(3,4-ethylenedioxythiophene) (PANI-PEDOT) films were electrodeposited on a transparent indium tin oxide glass electrode, which was pre-modified by two different methods. AuNS were electrodeposited at −0.2 V constant potential for 60 s using both the 1st method (synthesis solution consisted of 3 mM HAuCl4 and 0.1 M H2SO4) and 2nd method (15 mM HAuCl4 and 1 M KNO3) resulting in an improvement of optical contrast by 3% and 22%, respectively. Additionally, when using the 1st method, the coloration efficiency was improved by 50% while the switching time was reduced by 17%. Furthermore, in both cases, the employment of AuNS resulted in an enhancement of the electrochromic stability of the CPs layer. A further selection of AuNS pre-modification conditions with the aim to control their morphology and size can be a possible stepping stone for the further improvement of CPs electrochromic properties.
