Abstract
A kind of novel biodegradable poly(hexamethylene adipate) (PHMA) nanofibers with diameter of 100～700nm using a mixed solvent of 1,2-dichloroethane (DCE ) and trifluoroacetic acid (TFA) were obtained by electrospinning process in this paper. The morphology of electropun PHMA nanofibers were investigated by scanning electron microscopy (SEM). The results showed that the morphology, diameter and uniformity of the fibers were influenced by solvent ratio, solution concentration, applied voltage, capillary–screen distance and flow rate greatly. The finer and uniform nanofibers were electrospun from a mixed solvent of DCE and TFA with ratio of 70/30(w/w).
