Fabrication of polycaprolactone/polyethylene oxide nanofibers through electrospinning
Abstract
Polycaprolactone (PCL)/Polyethylene Oxide (PEO) blend nanofibers with diameters between 100 to 500 nm were successfully fabricated via the process of electrospinning. Three blends of PCL/PEO with by mass ratio of 75:25, 50:50 and 75:25, where the numbers represent the percent concentration of PCL and PEO in the blend respectively, were used in the experiment. The 75:25 blend has a mean diameter of 442 nm, 320 nm for the 50:50 blend and for 261 nm for 25:75 blend. Scanning electron micrographs revealed that increasing the percent concentration of PEO in the PCL/PEO solution decreases the mean fiber diameter of electrospun nanofibers. The experiment also revealed that the electrospinning set-up built in our laboratory is capable of fabricating polymer nanofibers.
