Effect of Humidity on the Surface Morphology of a Charged Jet

Effect of surface active agent on bubble-electrospun polyacrylonitrile nanofibers

“…There are many factors affecting the morphology and property of nanofibers obtained in the MBE process, including properties of spinning solution (such as solution mass fraction, viscosity and electrical conductivity), spinning parameters (such as voltage, drum rotation speed and working distance), and environmental parameters (such as temperature and humidity) [12][13][14][15]. According to our previous work [5,8,16], the electrospinning parameters were set as follows.…”

Experimental and theoretical study on the electrospinning nanoporous fibers process

“…The solvent removed from the polymer fluid jets involved the flash vaporization at the fiber surface and the diffusion from core to surface [15,33]. However, the formation of pores on the jets would waste the amount of energy which, otherwise, could be used to further stretch the jet into even smaller fibers [34]. As shown in Table 1, with further increased CF in the solvent mixtures, there had appeared evident pores and ever-increasing fiber diameters.…”

“…Before the primary jet splitting into two filaments, in A 1 area, u > u t , p < p 0 , the pores of the fiber flatten and its shape is oval. However, the instabilities and the formation of pores of the jets will waste the amount of energy; less kinetic energy of the moving jet means lower velocity of the jet [34]. When the jet moves from A 1 to A 2 area, its velocity is reduced to u t , then p ¼ p 0 in A 2 area, and the shape of the pores gradually become round, which means the ratio of pore width to pore length increases.…”

A particle suspension model for nanosuspensions electrospinning

“…The electrospinning process for fabrication of composite nanofibers is a multi-phase and multi-physics process. The electrospinning process has been studied experimentally and theoretically [17][18][19][20]. In recent years, many experimental studies have been conducted to understand the electrospinning process and a number of mathematical models have been developed for research mechanical mechanism of the process [21][22][23][24][25].…”
