摘要：
The basic mechanism of electrospinning is the rapid whipping of charged liquid jets, undergoing a chaotic "whip" process, and eventually the formation of disordered reticular fibers is continuously deposited on the receiving device. Firstly, the physical model of jet whipping is studied, which is to be established the physical model of solvent evaporation on the surface of the jet. The Jeffreys model and the Voigt model are used to describe the viscoelastic model of the unstable generating end and the end, and the unstable dynamic model is constructed. Finally, the coupling control equation is obtained, which has certain theoretical guiding significance for the development of electrospinning process.
