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.
