“…The disappearance of PANI and TiO 2 clusters with fully uniform dispersion in the TPU phase is observed in Fig. 2(e), which is mostly due to the de‐agglomeration of these conductive phases because of the incorporation of IL 20 . The dispersibility and coupling activity of IL with the conductive phases are solely responsible for such type of extraordinary behavior.…”

The conductive components are dispersed uniformly in the bulk of the system which is an important requirement for the improvement as well as reduction of noise during the measurement of dielectric properties.…”

Conductive polymer nanocomposites are enormously potent multifunctional lightweight flexible materials used in various electronic devices owing to their excellent dielectric characteristics with interesting relaxation behavior. In this present context, dielectric properties like dielectric permittivity (ε′), dielectric loss (ε″), AC conductivity (σac), real and imaginary impedance (Z′ and Z″), Nyquist plots, etc., of thermoplastic polyurethane/polyaniline/TiO2 (TPU/PANI/TiO2) nanocomposite films with 0–2 wt% TiO2 loading level have been studied. The dielectric analysis in the frequency range of 1 Hz to 1 MHz reveals that ε', σac, Nyquist plot as well as the relaxation behavior have been effectively tuned up to 1.5 wt% TiO2 loading level. The very high interfacial polarization of the dipoles at the interface is reflected in the ultrahigh value of ε′. The semicircular nature of the Nyquist plots is well explained by the cyclic movement of the charge and the high extent of charge storage. The significant improvement in dielectric properties in 1‐butyl‐3‐methylimidazolium hexafluorophosphate ionic liquid (IL)‐incorporated nanocomposite system reflects the coupling as well as dispersibility of IL. The reduction in ε′ and σac, and increase in bulk resistance with an increase in temperature indicate the positive temperature coefficient behavior of the developed nanocomposite systems. The adequate interaction between TiO2, TPU and PANI phases has been analyzed using X‐ray diffraction. The significant dispersing ability and coupling activity of the IL has been explored from micrographs obtained from a scanning electron microscopy study. © 2021 Society of Industrial Chemistry.

“…In the p -TSA medium, pure NZF is positively charged, so the anions of p -TSA get adsorbed on the surface of pure NZF. 43 Due to electrostatic interaction between the anions and cations, the aniline monomers are transformed into anilinium cations. 43 The NZF material is already dissolved in the p -TSA solution; thus, on adding APS, the anilinium cations start to polymerize from the NZF material surface.…”

“…Figure c shows the Nyquist plot of PANI/HPC. The semicircular arc in the plot indicates the non-Debye type and Warburg impedance, indicating the intermolecular electrical conduction. − The diameter of the semicircle represents the bulk resistance ( R ), which is R = 9.992 × 10 –6 Ω. A contact point between the semicircle and the x -axis represents the solution resistance ( R sol = 2.08 × 10 –5 Ω).…”

A polyaniline (PANI) composite was prepared through chemical polymerization of aniline in the cholesteric liquid crystal (CLC) state of hydroxypropyl cellulose (HPC). Polymerization and composite formation were simultaneously performed. Polarizing optical microscopy, scanning electron microscopy, electrochemistry, and optical spectroscopy were used to characterize the composite. Electron spin resonance and a superconducting quantum-interference device were used to investigate the composite’s magnetic properties. PANI in the composite exhibited a helical structure of the main chain as a result of the main chain growing in the direction of the LC orientation. The main chains of PANI were secondarily doped, thus they exhibited moderate electrical conductivity as a conducting polymer (PANI)/insulating polymer composite. Polarons (radical cations) distributed along the main chain with a helical structure are responsible for the composite’s magnetic spins. Consequently, the spins, like the helical structure, are delocalized. Because of the doping–dedoping of the PANI component, the composite exhibits excellent redox properties. The PANI/HPC composite’s potential applications in capacitors, electrochemical transistors, thermistors, and optical fibers were investigated.
