AbstractRegardless the low production rate, electrospinning remains the most widely used technique for nanofibers production. Thus, development of multi-jet technologies for electrospinning gives an opportunity to upscale and increase throughput, with only one drawback – electrostatic mutual jet repulsion effect. In present research we propose air blow-assisted multi-jet electrospinning system allowing production of nanofibers with yield, at least, tenfold higher than single jet electrospinning. The system produces nanofibers in two modes: multi-jet electrospinning and blow-assisted multi-jet electrospinning. Nanofibers morphology and size were investigated based on scanning electron microscope micrographs. The comparison of the two modes shows changes in nanofibers morphology from beaded structure to fine nanofibers, and the slight increase in fiber mean size with application of blowing assistance. What is more, blow-assisted multi-jet electrospinning allows to collect nanofibers in two times more focused way, lowering the product loss.
