This study described the preparation of discontinuous fibers of poly (N-vinylpyrrolidone) (PVP) containing metalloporphyrin (Manganese (III) tetrakis (Imethyl-4-pyridyl) porphyrin pentachloride) molecules using electrospinning method. SEM images showed that before adding the metalloporphyrin molecules, the electrospun nanofibers are straight and smooth, while after adding metalloporphyrin molecules into the PVP solutions, the SEM images clearly showed that there were two different types of fibers: the thinner fibrous phase and the thicker discontinuous fibers. The chemical composition of the resulting PVP/metalloporphyrin composite fibers was characterized by Fourier-transform infrared (FTIR) and energy dispersive X-ray (EDX) analysis.
