摘要
Abstract
Electrospinning has attracted much attention recently as a direct and consecutive fabrication technique for producing nano-scale to micro-scale fibers. In order to achieve deeper understanding of fiber change in the electrospinning process, this paper explores the mesoscopic simulation method of dissipative particle dynamics to create the electrospinning simulation system. The effect of viscosity on fiber falling velocity in different stages, the effect of chain length on fiber falling morphology and the effect of spring coefficient on end to end distance of polymer chains were successfully simulated. Melt-electrospinning process was theoretically studied and explored from the mesoscopic perspective. Deeper comprehension of scientific issues of this physical phenomenon was acquired.关键词
