Description

technical field [0001] The invention relates to the technical field of electrostatic spinning devices, in particular to an electrostatic spinning device for rotating liquid supply. Background technique [0002] Electrospinning technology is a technical method for preparing nanofibers. The principle is: the polymer solution will form a Taylor cone at the tip of the solution under the action of an electric field force, and then the Taylor cone tip will generate an electrospinning jet and stretch it through the electric field force. Complex processes such as solution volatilization, and finally nanofibers are obtained. Nanofibers prepared by electrospinning have the properties of small diameter and large specific surface area, and have wide application potential in biomedical materials, flexible electronics, micro-nano devices and other fields. [0003] How to achieve stable and efficient liquid supply in the electrospinning process has become a hot spot in the field of electr...
