“…The saturated hole mobility, threshold voltage, external quantum efficiency, photo-sensitivity, and photo-responsivity of OFET device were 9.5 × 10 −5 , cm 2 /V•s, −1.72 V, 1.16 × 10 2 A/W, and 7.33 × 10 4 A/W, respectively [72]. Furthermore, the PANI:CSA/SiO2 core-shell can be used for the corrosion protection coating for carbon steel substrates [45]. The PANI:CSA/SiO2 core-shell has shown nearly five orders magnitude higher corrosion resistance (2.24 × 10 7 Ω cm 2 ) when compared with the pristine silicon coating (5.37 × 10 2 Ω cm 2 ) [73].…”

“…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.

portable electronics, cell phones, electrical vehicles (EVs), aerospace, etc. For advanced batteries, higher and higher energy density and/or power density, long cycling stability, good device safety, and low-cost are the primary goals. Since the energy density is mainly dependent on the specific capacity and loading level of active materials (AMs), AMs usually dominate the volume and weight inside the batteries. Because of this, tremendous efforts have been focused on high-performance AMs. However, the electrochemical performance of energy storage devices (ESDs) is fundamentally determined by a collective contribution or teamwork of all the components: AMs, electrolyte, separator, conductive agent, binders, etc. More importantly, with the increasing interests on high-capacity AMs (e.g., silicon, sulfur, Li-rich cathode, etc.), it becomes very clear that the "traffic system" (i.e., the charge transport system) plays very critical roles in the performance of the high-capacity AMs. Take silicon anode for example, a durable and flexible conductive network inside the electrode composite has been vital for addressing the big volume change issue. In this case, high-performance binders and conductive agent that can generate advanced conductive network are the keys. [2] In addition, with the increasing interests on EVs and flexible electronics, building a powerful and robust charge transport system inside ESDs is an urgent and critical task to support fast charging/ discharging capability and even flexibility of ESDs. In short, with the fast development of energy storage technologies, EVs, cell phones, etc., there is a critical, urgent, and challenging task on building powerful and durable charge transport system in next-generation advanced ESDs. Charge Transport Inside ESDsThe thriving of big cities highly relies on a powerful traffic system that transports the people, foods, products, etc. Similar to this picture, ESDs are powered by the transportation of charges, including both ions and electrons. As illustrated in Figure 1a, one can analogize the charge transport system and AMs in the electrodes of ESDs to the traffic system and buildings (i.e., host system of people), respectively. This analogy example not only help to explain the relationship between The charge transport system in an energy storage device (ESD) fundamentally controls the electrochemical performance and device safety. As the skeleton of the charge transport system, the "traffic" networks connecting the active materials are primary structural factors controlling the transport of ions/electrons. However, with the development of ESDs, it becomes very critical but challenging to build traffic networks with rational structures and mechanical robustness, which can support high energy density, fast charging and discharging capability, cycle stability, safety, and even device flexibility. This is especially true for ESDs with high-capacity active materials (e.g., sulfur and silicon), which show notable volume change during cycling. Therefore, there is an ur...

“…12 Typical conducting polymers-polyaniline (PANI) and its composites have been studied recently due to its easy synthesis, low cost, easy doping and high pseudocapacitance. [13][14][15][16][17] However, the cycling stability of PANI is usually poor and its rate capability is low, which was mainly owing to the mechanical deterioration and the slow charge transfer. 18 The combination of 3D hierarchical graphene with controllable morphology conductive PANI can prevent the re-stacking of graphene, and graphene itself can inhibit the mechanical deterioration of PANI during charge and discharge.…”
