Effect of Solution Conductivity on the Morphology of Bubble-Electrospun Nanofibers

In this paper, we have bubble-electrospun PLA nanofibers to analyze and investigate the effect of different electrical conductivities by adding different amounts of LiCl into the PLA/DMF solutions on the morphology and diameter of the nanofibers. As a result, it is found that when the mass fraction of LiCl is 0.5%, we can obtain the smallest mean diameter of bubble-electrospun nanofibers with more smooth surface and uniform fineness. Moreover, both improving and reducing LiCl concentration brings on coarse nanofibers surface and poor diameter distribution.
