Structural and Morphological Studies of Electrospun Manganese-Doped Zinc Sulphide (ZnS: Mn) with Capping Agent L-citrulline/PVA Composite Nanofibers

Materials in the form of fibers are of great practical and fundamental importance. Combination of a high specific area, flexibility, and superior directional strength make nanofiber a preferred material for many fields such as biomedical applications including drug delivery as well as scaffold formation. Manganese doped Zinc Sulphide with capping agent L-citrulline is blended with high molecular weight Poly Vinyl Alcohol (PVA) and the resulting solution is electro-spun to get non-woven nanofibers. Structural Characterization has been done by X-ray diffraction (XRD) and Fourier Transform Infra-Red Spectroscopy (FTIR). The fiber obtained is of good crystallinity as evidenced by the intense XRD peaks. The morphology is analyzed using a Scanning Electron Micrograph (SEM). The SEM micrographs reveal smooth fibers with several millimeters in length and average diameters in the range of 645 nm. Studies point to the possibility of using the prepared fibers for bio-medical applications.
