Simple models of nanofiber motion in electro spinning
Result description
Fundamentals of electro-spinning representing a modern sophisticated technology for production of nanofibers in a very strong electric field are analyzed. From the physical viewpoint, the process of nanofiber formation is very complicated and many effects take place there, starting from nanofiber extraction from the melt or liquid. The second stage, movement of the nanofiber to the collector in electric field, is also not as simple as it appears. This stage is characterized by complex transformations whose complete measurement is not possible. In principle, the shape of nanofiber beam moving to the collector depends on the strength and distribution of electric field and its shape can be changed strongly by electrode changing. A simple electrostatic model includes all basic forces acting on the beam. Because of the process complexity, only qualitative agreement with the basic experimental results was achieved. In more complicated case the only explanation is possible. More sophistical m
