Abstract

In this study, the electrophoretic mobility of nanofibers in ethanol or in water was calculated by using both equations
from zeta potential values and related to their measured diffusion coefficients. Results showed that all samples in ethanol had
positive zeta potential values, whereas all samples in water, except sample 3 containing gelatin, had negative zeta potential
values. The samples with PVA or PVA-alginate had the most stable suspensions in water compared to other samples, regarding
zeta potential values. The electrophoretic mobilities calculated by using the Smoluchowski and Henry equations of samples
showed similar charge characteristics as zeta potential values. Gelatin might have charged by applied voltage during the
electrospinning process. When results were related to the diffusion coefficient values, it was observed that the higher
electrophoretic mobility and zeta potential values resulted in lower diffusibility. Moreover, adding limonene to the structure
decreased the electrophoretic mobility and zeta potential values, and increased the diffusion coefficient. The adding different
polymers revealed that molecular structure and charging behavior of the polymers are some of the most important factors on
the electrophoretic mobility and zeta potential of nanofibers.
