Diameter optimization of PVAc and TiO2 nanofibers using surface response method

In this work, we investigated the methods to optimize the morphology of PVAc and TiO
2
nanofiber membranes via electrospinning. The optimized fibers ’ morphology, crystallinity, and thermal stability were investigated, respectively. The optimization of fiber diameter was accomplished using the surface response method. A Box-Behnken design (BBD) experiment was developed to predict the parameter conditions necessary for achieving the minimum fiber diameter. The membranes ’ morphology was analyzed using electron scanning microscopy, while thermogravimetric analysis was employed to assess their thermal stability. Additionally, Raman spectroscopy was utilized to investigate the crystallinity of the PVAc/TiO
2
fibers.
