A particle suspension model for nanosuspensions electrospinning

Abstract

Polymeric composite nanofibers have been fabricated simply by the electrospinning of polymeric solutions containing a wide variety of suspended inclusions such as nanoparticles and nanotubes. The electrospinning process for fabrication of composite nanofibers is a multi-phase and multi-physics process. In this paper, a modified particle suspension model for electrospinning nanosuspensions is established to research the electrospinning process. The model can offer in-depth insight into physical understanding of the complex process which can not be fully explained experimentally.

Numerical analysis of the electrospinning process for fabrication of composite fibers

“…Fan et al [33] presented a fluid-mechanic model considering solvent volatilization to research nanopores structure formation in the ES process. Xu [34] established a modified particle suspension model to research the ES process. However, these studies were all about the establishment of mechanic models, which cannot offer in-depth insight into physical understanding of the ES process and also could not numerically simulate the jet flow in the ES process.…”

Mechanism study of highly ordered jets in an improved electrospinning process

“…A modified bubble-electrospinning by placing a positively charged ring between the bubble and the parallel electrode collector was also presented to fabricate highly aligned nanofibers in quantities [20]. In addition, it is very significant for understanding the movement of the jet and the formation mechanism of nanofibers in the ES process, resulting in the appearance of many related researches [21][22][23].…”
