Abstract

In this paper polylactide (PLA) nanofibers were successfully prepared via electrospinning using low toxic 1,4-dioxane and acetone as co-solvents. The morphology of nanofibers was studied by scanning electron microscopy (SEM) at the different weight ratios of co-solvent, concentrations of spinning solution, electrostatic voltages and collecting distance. Results indicate that the finer and uniform nanofibers were electrospun from the concentration of the spinning solutions at 8 wt.%, 1,4-dioxane and acetone with ratio of 40/60 (w/w), the spinning voltage at 20kV, the collecting distance at 180 mm and the extruding speed at 5 mL/h.
