Effect of Ultrasonic Vibration Power on Bubble-electrospun Nanofibers

Shaokai Li, Fujuan Liu, Fangfang Zheng, Yue Fang, Junhua Li


Biodegradable poly (vinyl alcohol) (PVA) polymer solutions with various concentrations are processed by ultrasonic vibration and bubble-electrospun to prepare nanofibers. It is shown that the ultrasonic vibration power has a significant impact on the viscosity and electrical conductivity of PVA solution, especially the morphology of the obtained nanofibers. Besides, when the concentration of spinning solution is kept at 11 %, the diameters of the nanofibers are measured. The novel approach can be used to improve solution spin ability and fiber fineness.
