Blow-assisted multi-jet electrospinning of poly-L-lactic acid nanofibers

摘要: Regardless the low production rate, electrospinning remains attractive technique for nanofibers in various fields. Thus, development of a multi-jet technologies gives an opportunity to scale up and increase throughput fibers production. However, exhibit one major drawback– electrostatic mutual jet repulsion issue. In present research, we propose air blow-assisted system allowing with yield, at least, tenfold higher than single electrospinning. The produces two modes: case latter, application sheath stream allows overcome These lead reduction deviation polymer solution jets, instabilities jets improvement control deposition. Nanofibers morphology size were investigated based on scanning electron microscope micrographs. comparison modes shows changes from beaded structure fine nanofibers, slight fiber mean when blowing assistance was applied process.
