Preparation of oligoaniline derivative/polyvinylpyrrolidone nanofibers containing silver nanoparticles

Oligoaniline derivative/polyvinylpyrrolidone nanofibers containing silver nanoparticles have been successfully prepared by electrospinning technique. Silver nanoparticles were prepared through reduction of Ag⁺ by oligoaniline derivative, and the process of redox was monitored by UV–vis spectra. The morphology of Ag-polymer blends nanocomposites and the distribution of Ag nanoparticles were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The electrochemical analysis of nanocomposites was checked by cyclic voltammetry (CV) in the 0.5 M H₂SO₄. In addition, the presence of Ag nanoparticles was indicated by X-ray diffractometer (XRD).
