Abstract

The invention discloses a mechanical stirring solution supply electrostatic spinning device. The mechanical stirring solution supply electrostatic spinning device comprises a container, a stirring impeller, a driving system, collecting devices and a power source. The stirring impeller is arranged in the container. The driving system can drive the stirring impeller to rotate around the axis so that a spinning solution or melt in the container can be stirred to form swirls. The container is provided with a side wall surrounding the stirring impeller, a solution storage cavity is formed inside the side wall, jet flow holes are formed in the portion, above the stirring impeller, of the side wall, and the collecting devices right face the jet flow holes. An electric field needed for jet flow generation can be formed by the power source between the collecting devices and the jet flow holes. The swirling phenomenon is applied to the spinning device, the spinning solution or melt can climb along the wall of the container under the action of stirring centrifugal force, if the jet flow holes are located in the high-voltage electric field, the jet flow holes can generate Taylor cones and form jet flows, the consumed spinning solution can be constantly implemented by the climbing spinning solution, and therefore continuous and automatic solution supply is achieved. Due to the fact that stable, continuous and automatic solution supply can be achieved, large-scale industrial production of nanofilms is facilitated.

Description

technical field [0001] The invention is used in the technical field of electrospinning, and in particular relates to an electrospinning device for mechanical stirring and 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 a wide range of application potentials in biomedical materials, water filtration, battery separators and other fields. [0003] How to achieve efficient liquid supply in the electrospinning process has become a hot spot in the field of elec...
