“…The vibration appeared at 1248 cm -1 assigned as a C-N + • on the polaron lattice, this band indicated the characteristic of PAni in the protonated form [18]. The strong and broadband on PANI synthesis at 1140 cm -1 was associated with the vibrations of Q=NH + -B or Q-NH •+ -B [17]. So, we can conclude that the PAni synthesis presented in emeraldine form.…”

“…In general, the polymerization of PAni mechanism takes place in several stages, namely (i) initiation, (ii) dimerization and (iii) polymerization [17,20]. The first step, the use of acidic media in polymerization not only to help increase the solubility of aniline but also to form anilinium species which known to be easier to oxidize compared with neutral aniline building a dication radical anilinium by releasing one electron, which balanced with aniline cation radical ( Figure 2).…”

Here, we report the effect of various drying temperature of Polyaniline (PAni) on battery PAni|Zn performance. PAni was synthesized using the electrodeposition method on the surface of the graphite sheets (GS), at 0.7 V relative to the saturated Ag/AgCl. PAni is dried with various temperature, 25, 80, 120, and 180 o C, respectively. PAni was characterized by Raman spectroscopy; then the performance Pani battery was studied in a rechargeable battery system. The measurement results found the PAni|Zn battery with 25 o C temperature drying of PAni was a good performance which the capacity density stable at 175-105 mAh g-1 until 100 cycles. Raman study showed that high-temperature drying resulted in a cleavage peak at 1188 cm-1 and increased peak intensity at 1495 cm-1. This vibrational mode appears as a stretching ν(C-C) on the semi quinonoid ring and ν(C=N) on the quinoid ring. This phenomenon indicated the changing structure of PAni to be Emeraldine base form.

“…The peaks at 1436 cm -1 to 1411 cm -1 were assigned to the C〓C stretching of quinoid ring [43,[45][46][47][48]. The peaks at 1315 cm -1 to 1307 cm -1 confirmed the protonated state of PANI with C-N stretching [46][47][48][49][50]. The results confirmed that PANI was successfully polymerized while maintaining the cellulose structures of BC and CC.…”

This study aimed to produce cellulose-based conductive fabrics with electrical conductivity and flexibility. Bacterial cellulose (BC) and three chemical cellulose (CC), namely methyl cellulose (MC), hydroxypropyl cellulose (HPMC) and carboxymethyl cellulose (CMC) were in situ polymerized with aniline and the four conductive cellulose fabrics were compared and evaluated. Matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy analysis confirmed that three CC-PANI composites displayed longer and more stable polymerization pattern than BC-PANI because of the different polymerization method: bulk polymerization for BC-PANI and emulsion polymerization for CC-PANI, respectively. The electrical conductivity of BC-PANI and CC-PANI were ranging from 0.962 × 10 −2 S/cm to 2.840 × 10 −2 S/cm. MC-PANI showed the highest electrical conductivity among the four conductive cellulose fabrics. The flexibility and crease recovery results showed that MC-PANI had the highest flexibility compared to BC-PANI, HPMC-PANI, and CMC-PANI. These results have confirmed that the electrical conductivity and flexibility were influenced by the type of cellulose, and MC-PANI was found to have the best performance in the electrical conductivity and flexibility.

“…The solid aniline hydrochloride salt is preferred over the liquid aniline monomer as the salt is less toxic and easier to transport. [ 67,68 ] The geometric area of CNT employed for PANI electrodeposition was 1.25 cm 2 (2.5 × 0.5 cm). The resulting sample was defined as CNT/PANI.…”

A high‐rate capability carbon‐encapsulated polyaniline (PANI) composite is fabricated by a novel electrodeposition method of polyaniline on a carbon nanotube (CNT) forest, grown on carbon paper. This is followed by coating of an amorphous carbon layer via hydrothermal carbonization (HTC) of glucose, forming a three‐layer structure. We demonstrate that a slow scan rate, voltage‐restricted electrodeposition process can be used to produce a uniform PANI coating on individual CNTs throughout the network. The CNT forest structure offers excellent electronic and structural connection for the PANI nanofiber network, while the coating of amorphous carbon reduces electrode resistance, promoting enhanced electrochemical performance and reinforced structural stability during charging and discharging. The as‐prepared CNT/PANI/HTC composite exhibited a high specific capacitance of 571 F g−1 at 1 A g−1, and 557 F g−1 at 100 A g−1,whilst demonstrating a record rate capability of 98% capacitance retention, when the current density is increased 100‐fold. This advanced rate performance indicates that a slow electrodeposition process produces an electrochemically stable three‐layer composite with enhanced diffusion kinetics. Hence, the method developed in this work establishes further control on the electrochemical deposition of energy storage materials, for high‐rate capability.
