This paper presents a successful preparation of SEBS (a copolymer polystyrene‐block‐poly (ethylene‐ran‐butylene)‐block‐polystyrene) and SEBS‐CB (SEBS‐Carbon Black nanoparticles) coatings on a copper surface following a well‐defined immersion protocol. Such coatings′ protection capacity was tested in a 3 wt% NaCl medium using potentiodynamic polarization, cyclic voltammetry (CV), and electrochemical impedance techniques (EIS). The electrochemical measurements indicate that SEBS and SEBS‐CB are cathodic‐type inhibitors mainly hindering the diffusion of oxygen molecules toward the copper substrate. It also indicates the decrease in chloride ion attack on the coated copper layer. Not only that, but it also affirms the decrease in CuCl2- ${{{\rm \ }{\rm C}{\rm u}{\rm C}{\rm l}}_{2}^{-}}$ ‘s transport to the bulk solution, resulting in our sample being further protected at more positive potential. Cu‐SEBS‐CB electrodes showed a slight improvement in corrosion protection compared to Cu‐SEBS electrodes. π‐π stacking was associated with improving the performance of these coatings. The keys functions of incorporating CB are improving the electrode conductivity and having a denser and more compact coating than that without CB. The order of inhibition efficiency obtained by potentiodynamic polarization is in good agreement with the results achieved by electrochemical impedance spectroscopy. Also, the inhibition efficiency of Cu‐SEBS and Cu‐SEBS‐CB increases with increasing the ratio of SEBS. Adsorption of SEBS and SEBS‐CB on copper surface follows the Langmuir isotherm.

“…Furthermore, PANI composites that were combined with PEO and PVP were also utilized as gel electrolytes for offering catalytic and hole-transporting properties on the QS-DSSCs ( Figure 10f) [49][50][51][52]. While considering these results, it was evident that the PANI composites combined with water-soluble polymers are appropriate for constructing high-performance and solid-state energy storage and energy conversion devices [43][44][45][46][47][48][49][50][51][52]. According to Li et al, a PANI-PVA hydrogel with a tensile strength of 5.3 MPa can be readily produced by crosslinking reactions between PANI and PVA chains through boronate bonds [53].…”

“…Other hydrophilic polymers, such as carboxymethylcellulose (CMC) [41,42,44,45], styrene-butadiene rubber (SBR) [43][44][45], polyacrylic acid (PAA) [46][47][48], polyethylene glycol (PEG) [47], polyethylene oxide (PEO) [49][50][51], poly(vinyl pyrrolidone) (PVP) [52], and polyvinlyl alcohol (PVA) [53], and these water-soluble polymers significantly improve the dispersion of PANI in the aqueous phase. In addition, when these water-soluble polymers are used as binders for electrodes or electrolyte membranes, the suppression of undesirable volumetric expansion and durability of the device can be improved [43][44][45][46][47][48][49][50][51][52][53]. According to Bilal et al, the gravimetric capacitance of a three-electrode capacitor while using the GO-PANI/CMC composite was 1721 F g −1 , which suggested that the dispersion of active materials highly affect the resulting electrochemical performances [41].…”

“…Although the protonated portions of CP chains can be dissolved in water, the overall solubility in water is limited due to the non-protonated portions of CP chains being hydrophobic . The CP chains were combined with hydrophilic polymers, such as poly(4-styrenesulfonate) (PSS) , carboxymethylcellulose (CMC) [41][42][43][44][45], styrene-butadiene rubber (SBR) [43][44][45], polyacrylic acid (PAA) [46][47][48], polyethylene glycol (PEG) [47], polyethylene oxide (PEO) [49,50], poly(vinyl pyrrolidone) (PVP) [51], and polyvinlyl alcohol (PVA), and intermolecular components of the conductivity of PANI. The PANI:CSA offers strong hydrogen bonding interactions with the −SO 3 H group of CSA and −OH group of m-cresol, which enables excellent compatibility with the m-cresol [5,6,15,16].…”

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.

The present research work undertakes the investigation of preparation of the polystyrene‐block‐poly (ethylene‐ran‐butylene)‐block‐polystyrene triblock (SEBS) copolymer coating on a copper surface (Cu‐SEBS) following a well‐defined immersion protocol. The SEBS ratio, drying temperature (Temp), and drying time (time) are the factors for the determination of the immersion protocol of the Cu‐SEBS electrode's preparation. To evaluate the effects of these factors on the anticorrosive behaviour of copper in NaCl 3 % solution and to determine the best conditions to produce a protective SEBS film on the copper surface (low corrosion rate), we used the experimental design and the central composite design (CCD). The response surface methodology (RSM) was used in this study as an optimization method and the Statgraphics software was used to treat experimental design data. The corrosion rate of Cu‐SEBS at the different runs of the experimental matrix was measured by voltammetry around the open circuit potential (OCP) (ΔE=±50 mV vs SCE). The analysis of variance, the Pareto graph and the figure of the main and combined effect of the experimental factors show that the SEBS rate is the most significant factor. The linear effect of time and Temp, the quadratic effect of SEBS ratio, and the interaction between SEBS ratio and the drying temperature is, even though important, less significant. The optimized parameters were determined to obtain the lower corrosion rate, which was a 3.059 % of SEBS ratio, 70.18 °C of drying temperature, and 21 min of drying time. Then, to confirm the model, an electrochemical investigation of SEBS‐coated copper at optimal conditions of immersion protocol (Cu‐SEBS‐Opt‐Cond) was successfully applied in a 3 wt % NaCl aqueous solution. The corrosion rate of Cu‐SEBS‐Opt‐Cond was obtained by voltammetry around the open circuit potential (OCP) equal 0.00023 mm year−1 which is close to that found by the experimental design. The measures of voltammetry around OCP, cyclic voltammetric (CV), and electrochemical impedance spectroscopy (EIS) showed that the Cu‐SEBS‐Opt‐Cond electrode exhibited more stability and a much higher corrosion resistance than that observed for bare copper.
