“…Moreover, this characteristic peak in the bidimensional contour map gradually narrowed with the increasing discharge time, suggesting the improved crystallinity of PANI electrode as the reduction reaction going on. [ 32 ] From the view of Zn anodic reaction, metallic Zn was oxidized to Zn 2+ and subsequently dissolved into the electrolyte, so that a peak at ≈22.5 o appeared in XRD pattern, corresponding to the (200) lattice plane of the new phase product of Zn 5 (OH) 8 Cl 2 ·H 2 O (JCPDS:07‐0155). [ 33 ] During the discharging process, The peak enhanced along with the gradual oxidation reaction (Equation (1)).…”

High‐performance all‐solid‐state rechargeable batteries with highly wearable, deformable, and waterproof features have attracted considerable attention for their promising applications in next‐generation wearable electronics. Herein, a flexible all‐solid‐state in‐plane Zn‐polyaniline (PANI) micro‐battery with concentric circle structure is reported by directly electrodepositing both positive and negative electrode materials on tyrene‐isoprene styrene rubber (SIS) substrate. As‐fabricated battery delivers a high specific area capacity of 250 µAh cm−2, a high energy density (0.25 mW h cm−2) and a high power density (0.99 mW cm−2) as well as excellent cyclin stability (68% capacity retention after 1200 cycles). More importantly, the concentric circle structured micro‐battery exhibits superior mechanical flexibility, reasonable stretchability, outstanding waterproof ability, and temperature resistance up to 80 °C and excellent integratability with wireless charging coils.

“…In PANI/rGO in situ composite, there are signi cant differences in the relative intensity of peak characteristics for PANI can be noticed, showing that the crystalline nature of PANI is affected by the reducing agent. It also points to the fact that the reduction of PANI/GO by hydrazine hydrate in uences the loss of crystallinity nature of PANI [14].…”

Polyaniline (PANI) as a known conducting polymer, exists in different forms, each having its properties and technological applications. PANI and PANI/Graphene Oxide (PANI/GO) composites with different compositions of GO were prepared by in-situ polymerization techniques. The synthesized PANI/GO composites were reduced to PANI/reduced Graphene Oxide (PANI/rGO) via in situ polymerization method. PANI/rGO composites were synthesized by ex-situ polymerization technique also. This research work attempts to do a comparative study of the synthesis and properties of graphene-based PANI nanocomposites. It has been characterized by X-Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR). The prime characteristic peaks from FTIR were analyzed and observed for the formation of nanocomposites. The anti-microbial properties of the polymer composites were investigated by the Agar well diffusion method using two gram-positive and two gram-negative bacteria – Bacillus, Staphylococcus, and Pseudomonas, Escherichia coli. Pristine PANI shows an inhibition zone in all bacteria than PANI/GO. PANI/rGO ex-situ has more antibacterial activity than PANI/rGO in-situ composite.

This study introduces a novel electrode material featuring a core‐shell intercalation structure. The material was synthesized using a simple and scalable method suitable for industrial replication. The outer layer of the electrode material comprises polyaniline, enveloping a nuclear structure composed of manganese dioxide and nickel oxide. This core‐shell configuration is then integrated into the lamellar structure of graphene oxide, resulting in the formation of PANI@(MnO2 + NiO)@GO composite. The combination of polyaniline, metal oxides, and graphene oxide demonstrates robust adsorption capacity, leading to the development of a three‐dimensional stable structure between the core and the shell. Additionally, graphene oxide contributes to the bilayer capacitance of the composites, resulting in simultaneous multiple synergistic effects and improved charge storage capacity. Electrochemical characterization reveals exceptional properties of this composite material, exhibiting a specific capacitance of 396 F g−1 at a current density of 0.5 A g−1 in a three‐electrode configuration. Furthermore, the material retains 82.6% of its capacitance after undergoing 3000 consecutive charge/discharge cycles. Calculations estimate the energy density and power density of this composite in a supercapacitor employing 1 M Na2SO4 electrolyte to be 43.2 W h kg−1 and 249.99 W kg−1, respectively.
