A high speed dual electrode mode electrospinning was developed in this study. With coexistence of both positively and negatively charged nozzles, the electrospun fibers interact and bridge grafting between nozzles, interconnect with each other, and are stretched on a movable collecting roll. The results demonstrate that a highly intertwined, three-dimensional isotropic network structure can be obtained by using the dual electrode mode. Moreover, the productivity was increased more than 170 times compared to that using the conventional single electrode mode process, which is essential for commercialization of the electrospinning process.
