Abstract: A novel, high speed electrospinning process, dual electrode mode electrospinning was developed. With coexistence of both positively and negatively charged nozzles, the electrospun fibers interact between nozzles, interconnect with each other, and are stretched on a movable collecting roll. By electrospinning the biodegradable polymer via the dual electrode mode process, a highly intertwined, mathematics mode was obtained. Moreover, the productivity was increased more than 10 times in comparison to that by using the conventional single electrode mode process, which is essential for commercialization of the electrospinning process.
