| Summary: | The electrospinning process is a very important technique for fabricating polymeric nanofibers by apply�ing external electrostatic forces. This study reports on the modeling of the electrospinning process of
polyvinylidene fluoride (PVDF) and the immobilized ZnO/Ag2CO3/Ag2O using response surface method�ology (RSM) based on the central composite design (CCD). The individual and interaction effects of the
most effective variables, such as applied voltage (6.5, 8 and 9.5 kV), nozzle-collector distance (10, 12.5
and 15 cm) and ZnO/Ag2CO3/Ag2O photocatalyst concentration (0.1, 0.8 and 1.5 g), have been evaluated
on the porosity response of the nanofiber. The analysis of variance (ANOVA) confirmed that the spinning
voltage was the main variable affecting the average porosity of the composite PVDF nanofiber. The
regression coefficient between the variables and the mean porosity (R2 = 0.8321) indicates acceptable
evaluation of experimental data by quadratic polynomial regression. |
