Polyaniline/polyvinylpyrrolidone nanofibers via nozzle‐free electrospinning

Abstract

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.

“…14 The precursor nanofibrous membranes can be produced by many methods, but electrospinning is the most versatile process for producing nanofibers because of its ease of application and possible use of a wide variety of polymers. [15][16][17][18] During the electrospinning process, a polymer solution or a polymer melt is subjected to a high voltage, which causes the formation of an electrically charged jet of fluid moving toward a grounded collector. In the meantime the solvent of the solution evaporates or if a polymer melt is used the melt begins to solidify.…”
