AB - The near-field electrospinning is considered as one of the most effective  techniques to direct-write aligned fibers which can be applied to various  high-tech areas, including energy harvester, tissue engineering, and  wearable sensors. For large area aligned pattern printing, the multi-nozzle  electrohydrodynamic print-ing is an efficient method to enhance  productivity. As a branch of electrohydro-dynamic printing technology, the  near-field electrospinning is a crucial concern to make an investigation for  the formation of aligned nanofibers. Here we fabricated various  nanostructures from beaded fibers to aligned fibers and crimped fibers by  the double-nozzle near-field electrospinning process. We found three key  parameters affecting the process, including the collector speed, the applied  voltage, and the electrode-to-collector distance, and the collector speed is  the key factor affecting the crimped frequency. This paper provides a  reliable experi-mental basis and theoretical guidance for the multi-nozzle  near-field electrospin-ning to accurately direct-write microfibers and  nanofibers.
