Objective: The objective of the current work is to synthesize the conducting polymer, i.e. polyaniline electrodes, with different reaction times using the chemical bath deposition (CBD) method. The further study involves its effect on structural, morphological, and electrochemical characteristics of the PANI electrodes. Methods:The CBD method is used to synthesize the PANI electrodes. The analysis of the electrodes was carried out using X-Ray diffraction, contact angle, FESEM with EDX, Fourier-transform infrared spectroscopy, and electrochemical characterizations. Results:The structural and wettability analysis confirmed the amorphous and hydrophilic properties of the PANI electrodes. The contact angle increased with an increase in the reaction time of the PANI electrodes. The morphological images of all samples showed that the thickness of the interconnected nanofibres increased with the deposition time. Electrochemical analysis of the PANI electrodes was carried out by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy. The evaluated highest value of specific capacitance (SC) by CV was 601F/g at 5mV/s in 1M KOH. GCD provided specific energy of 9.10Whg −1 , specific power of 22kW kg −1, and an efficiency of 92.89%. Conclusion:It is feasible to synthesize PANI samples with the CBD method. The physical and electrochemical properties of electrodes prepared at different deposition times change with increasing deposition times. Deposition time does not affect the amorphous nature of the sample, and the sample deposited for 60min exhibited the highest SC 601F/gm at 5mVs -1 .

“…A modified version of the chemical bath deposition is the fabrication of the layers by following a scheme based in ionic layer adsorption followed by a reaction process [69]. This method relies on the succesive inmersion of the substrates in solutions containing precursor ionic species of those that are expected to form the assembled layers upon a chemical reaction [70].…”

The construction of nanostructured materials for their application in electrochemical processes, e.g., energy storage and conversion, or sensing, has undergone a spectacular development over the last decades as a consequence of their unique properties in comparison to those of their bulk counterparts, e.g., large surface area and facilitated charge/mass transport pathways. This has driven strong research on the optimization of nanostructured materials for the fabrication of electrochemical devices, which demands techniques allowing the assembly of hybrid materials with well-controlled structures and properties. The Layer-by-Layer (LbL) method is well suited for fulfilling the requirements associated with the fabrication of devices for electrochemical applications, enabling the fabrication of nanomaterials with tunable properties that can be exploited as candidates for their application in fuel cells, batteries, electrochromic devices, solar cells, and sensors. This review provides an updated discussion of some of the most recent advances on the application of the LbL method for the fabrication of nanomaterials that can be exploited in the design of novel electrochemical devices.

Development of well-designed electrodes is the key to achieve high performance supercapacitors. Therefore, as one of the effective methods, a layer-by-layer (LBL) approach is often fruitfully employed for the fabrication of electrode material. Benefiting from a tunable parameter of the LBL approach, this approach has paved a way to design a highly ordered nanostructured electrode material with excellent performance. Conducting polymers (CPs) are the frontrunners in supercapacitors and notably, the LBL assembly of CPs is attracting extensive attention. Therefore, this critical review covers a comprehensive discussion on the research progress of CP-based composites with special importance on the LBL approach predominately for supercapacitors. Following a brief discussion on supercapacitors and CPs, the most up-to-date techniques used in LBL are highlighted.
