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.

静电纺丝的基本机理是带电液体喷射流的快速搅动，经历了混乱的“搅动”过程，最终形成无序的网状纤维不断沉积在接收装置上。首先，研究了射流搅动的物理模型，以建立射流表面溶剂蒸发的物理模型。用Jeffreys模型和Voigt模型描述了不稳定产生端和产生端的粘弹性模型，并建立了不稳定动力模型。最后得到耦合控制方程，对电纺工艺的发展具有一定的理论指导意义。
