摘要

To broaden the applications of the electrospinning technique, high throughput is one of the primary goals of many researchers. To overcome the throughput limitation, we have introduced coaxial grooved nozzles. By using a coaxial grooved nozzle and two fluids, including polyethylene oxide (PEO), we are able to achieve stable multi-jet operation and relatively high throughput. The multi-jets are initiated by the multi-jet mode of the inner fluid, and share the total flow rate of the polymer solution. We have investigated the operating conditions for various flow rate combinations of two fluids. The morphology of the resulting nanofibers is uniform without bead formation. The fibers have an average diameter of about 350 nm. POLYM. ENG. SCI., 58:416-421, 2018. (c) 2017 Society of Plastics Engineers
