“…SEM of PANI demonstrates the growth and interlocking of PANI particles (Figure 2 (a)). The surface of PANI is found uneven and irregular, similar phenomena have also been reported in the literature [27]. As seen in Figure 2(b), the surface area of Ni-PANI composite is larger than PANI.…”

“…Then calculated amount of APS was dissolved in 2 M aqueous HCl solution, and added drop wise to the NiCl 2 mixed aniline solution under continuous stirring for well mixing and continued for 45 min to prepare Ni/PANI composite. Finally the polymerization was completed, and the PANI composite was washed and dried following the procedure described in our previous studies [ 27 ]. Similarly, Cu/PANI, Mg/PANI, Carbon nanofiber (CNF)/PANI, and Benzene sulphonic acid/PANI composites were prepared in this study.…”

This study focuses on synthesis of polyaniline composites and application as electrode material in the fabrication of hybrid supercapacitors. Hybrid supercapacitors were fabricated using aluminum foil as current collector, and conductive Polyaniline (PANI) composites as electrode materials. Cobalt oxide (Co 2 O 3 ), ammonium peroxydisulfate (APS) were used along with PANI in the preparation of electrodes of the supercapacitor. Polyaniline and its various composites were used in the cathode and activated carbon in the anode (positive electrodes) of the asymmetric hybrid supercapacitor. Electrochemical performance of the supercapacitors has been evaluated on the basis of capacitive properties (i.e. capacitance, energy density and power density). Area of the supercapacitor, applied voltage for charging and composition of cathode materials have been optimized in this study. The optimum area of the supercapacitor was found 30 cm 2 at optimum voltage 5 V. The result showed that supercapacitor fabricated using polyaniline (PANI) as cathode material with Al foil as current collector provided highest capacitance of 249 F/g, Energy density of 31 Wh/kg and Power density of 18 W/kg. Among various PANI composites (Ni-PANI, Cu-PANI, CNF-PANI) synthesized in this study, Ni-PANI composite showed highest capacitance of 336 F/g, energy density of 42 Wh/kg, and power density of 31 W/kg. The result indicates that Ni-PANI composite has high potential as cathode materials for the hybrid supercapacitor.

“…Whereas Fe in γ ‐Fe 2 O 3 has electronic configuration [Ar] 3d 6 4s 0 (instead of [Ar] 3d 6 4s 2 ) because of this it can be easily 3d electrons to attain Fe (II) and further it undergo self‐organized Fe(II)‐PAni composite 25 . It helps join two PAni chains as bridge between them (Scheme 1) and earlier researchers has been reported as doped form Fe(II)‐PAni 26,27 . The sulphonic acids doping improves π–π interaction than that of γ ‐Fe 2 O 3 cocomposite, that is, Fe‐PAni (where Fe loses electrons to attain stable configuration).…”

Due to this acid doped PAni fluorophores fluorescent intensity slightly increases, which is more than that of Fe-PAni and PAni.…”

The detection techniques for traces of energetic materials (EMs) is achieved using fact interaction between fluorescent polymers and EMs. Researchers have designed various fluorophores for explosives detection worldwide. In present study, PAni, DBSA doped PAni (D‐PAni), γ‐Fe2O3PAni composite (Fe‐PAni), were synthesized and collectively used terminology as modified PAnis. This were employed for trace detection of EMs like TNT, RDX, PETN, and HNIW/CL‐20 and compared outcome with our earlier results of doped PAnis. All the synthesized PAnis were characterized by FT‐IR, X‐ray diffraction (XRD) and resonance Raman studies, UV–Visible, and photoluminescence (PL). The PL studies showed that quenching is selective and sensitive at ppm level (LOD about 0.04–1.50 μ mL−1) and Fe‐PAni emerged as a potential sensor (LOD; 0.092 ± 0.07 μ mL−1). The formation of polaron from bipolaron, the existence of exciton and intermolecular interactions were confirmed and evaluated from the spectrochemical studies.
