Morphological and Photocatalytic Properties of PVA/TiO2 Nanocomposite Fibers Produced by Electrospinning
In this study, PVA/TiO2 anatase nanocomposite fibers were prepared successfully by electrospinning. The nanofibers were characterized by SEM, XRD, Raman spectroscopy, EDS, TEM and UV-Vis diffuse reflectance spectroscopy. The characterization showed that the average diameters
obtained are dependent of the total loading used. The TiO2 loading showed to be effective in the nanocomposite, changing the UV absorbance but significantly accelerating the degradation of the polymer. This aspect may be useful in order to improve the biodegradability of this polymer
by reducing chain lengths.
