“…In PANI/PVP nanofibers spectra, this band gradually shifted to a mode of lower frequency stretching. This shift can be attributed to a rise in the stiffness of PVP rings and may also be seen as proof of the existence of a hydrogen connection between PVP and PANI 76,78 …”

“…In addition, several bands are also seen in the range between 1245 and 1520 cm −1 . Both the band at 1443 cm −1 and the band at 1292 cm −1 are caused by the stretching of the molecules (NC)O and (CN)C, respectively 78,79 …”

“…Both the band at 1443 cm À1 and the band at 1292 cm À1 are caused by the stretching of the molecules (N C) O and (C N) C, respectively. 78,79 The PVP and PANI/PVP nanofibers spectra are almost identical because higher concentrations of PVP are used to prepare the PANI/PVP electrospinning solution. The pure PVP nanofiber spectrum exhibits one charband at 1644 cm À1 , which corresponds to free carbonyl, while the PANI powder spectra exhibit no absorptivity in the carbonyl region.…”

Polyaniline (PANI) in its emeraldine base (PANI‐EB) and salt (PANI‐ES) forms was combined with polyvinylpyrrolidone (PVP) to produce nanofibers in a one‐step electrospinning process using a nozzle‐free electrospinning setup for the first time. The surface morphologies and chemical structure of the composite nanofibers were characterized by scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transform infrared spectroscopy—attenuated total reflectance (FTIR‐ATR), and energy‐dispersive X‐ray spectroscopy (EDX). Four PANI/PVP electrospun nanofibers with different PANI concentrations were prepared to investigate the effect of PANI concentration on the structure and properties of the nanofibers. The incorporation of different contents of PANI‐EB and PANI‐ES in the PVP solution and their impact on the fiber morphology were investigated.

In this work, a chemical grafting polymerization method was employed to synthesize EHPMC-g-PANI self-supporting films. Polyaniline (PANI) was grafted onto hydroxypropyl methylcellulose (HPMC) modified with epichlorohydrin (EPHMC) to obtain an EHPMC-g-PANI aqueous dispersion, which was subsequently dried to form the self-supporting films. The introduction of HPMC, with its excellent film-forming ability and mechanical strength, successfully addressed the poor film-forming ability and mechanical properties intrinsic to PANI. Compared to in situ polymerized HPMC/PANI, the EHPMC-g-PANI exhibited significantly improved storage stability. Moreover, the fabricated EHPMC-g-PANI films displayed a more uniform and smoother morphology. The conductivity of all the films ranged from 10−2 to 10−1 S/cm, and their tensile strength reached up to 36.1 MPa. These results demonstrate that the prepared EHPMC-g-PANI holds promising potential for applications in various fields, including conductive paper, sensors, and conductive inks.
