A bubble electrospinning system for preparing composite fiber materials

Abstract

The invention discloses a bubble electrostatic spinning system for preparing a composite fiber material. A spinning cylinder and an air cylinder in an internal-external nested manner are adopted as spinning devices; different solutions are separated and conveyed to the closed spinning cylinder through a first liquid conveying pipeline; and the solutions are uniformly mixed through the rotation of the air cylinder to realize batch production. A liquid supply device is closed, the property change of the spinning solution is avoided, the spinning quality is guaranteed, and environmental pollution is reduced. The spinning holes in the spinning cylinder are designed in equal-interval vertical axial arrangement, and mutual influence of bubbles generated at any adjacent spinning holes is effectively avoided; and meanwhile, at least one vent hole stays on the same horizontal plane with the spinning holes so as to guarantee normal spinning at each spinning hole and improve the yield of the micro-nano composite fiber material. A receiving device is arranged in a roller manner and circles the spinning cylinder, so that the fiber receiving area is effectively increased, and continuous batch production is possible.

Problems solved by technology

However, in the current bubble electrospinning technology, when the composite fiber material is prepared, the spinning solution is exposed to the air, which leads to changes in the properties of the solution, thereby reducing the spinning efficiency, and the interaction of multiple bubbles leads to the Taylor cone interaction caused by bubble rupture. , Solutions with different functions cannot be completely and uniformly mixed, which makes it impossible to achieve larger-scale mass production of micro-nano composite fiber materials

[0005] In view of the above technical problems, it is necessary to provide an effective air bubble electrospinning device for preparing composite fiber materials to solve the problems of mutual influence between air bubbles and different spinning solutions that cannot be completely uniformly mixed in the air bubble electrospinning process, and realize micro Mass production of nanocomposite fiber materials
