Abstract
Polycaprolactone (PCL), Polyethylene Oxide (PEO) and blends of PCL/PEO nanofibers namely, 75/25, 50/50 and 25/75, were successfully fabricated via the process of electrospinning under a constant applied voltage of 20 kV. Scanning electron micrograph revealed that pure PCL and pure PEO have mean diameters of approximately 366 nm and 337 nm respectively, while the three blend ratios of PCL/PEO, namely 75/25, 50/50 and 25/75, have mean diameters of 442, 319 and 261 ma respectively. The smallest individual fiber of 25/75 PCL/PEO blend has a diameter of 77 nm. One way analysis of variance (ANOVA) with 1% level of significance showed that the mean diameters of the three PCL/PEO nanofiber blends do not have significant difference. Structural characterization using Fourier Transform Infrared Spectroscopy verified that the nanofibers produced were indeed PCL, PEO and blends of PCL/PEO. The absence of new peaks in the electrospun PCL/PEO indicated that the fabricated nanofiber was a composite material.
