Abstract :
Poly(vinylidene fluoride) (PVDF) nanofibers were prepared via
electrospinning process. Several different factors influence on this
process and application of experimental design for its optimization is
of great importance. The central composite design (CCD) was used
for planning and optimizing of the experiments and also, the analysis
of variance (ANOVA) was employed for the statistical validation of
regression models. In this research, we found optimal condition for
the effects of four factors, i.e. PVDF concentration, flow rate,
voltage and interval on the fiber diameter. The model indicated that
the flow rate (negatively) and solution concentration (positively)
influence extremely on the fiber diameter, whereas the voltage and
interval influence equally together on the response (negatively).
