Abstract

The invention provides an air bubble electrostatic spinning device. The air bubble electrostatic spinning device comprises a liquid storage tube, a mixing tube, an air bubble tube and an electrostatic generator; the liquid storage tube is connected with the mixing tube; the mixing tube is connected with the air bubble tube; the electrostatic generator is arranged at the tail end of the air bubble tube; a liquid adding groove is arranged above the liquid storage tube; a feeding groove is arranged above the mixing tube; a spinning solution and an additive can be added in a spinning process at any time; a mixing device is arranged in the mixing tube; air blowing tubes are arranged at two sides of the air bubble tube; after being injected into the liquid storage tube through the liquid adding groove, the spinning solution enters the mixing tube; the additive is added through the feeding groove; the spinning solution and the additive are mixed evenly; the mixture enters the air bubble tube; the spinning solution which forms air bubbles is converted into jet flows at the tail end of the air bubble tube through static electricity; the jet flows are ejected; and ultimately, nanofibers can be formed. Thus, spinning time after the spinning solution and the additive are mixed together can be shortened, and the uniform mixing and stability of the original spinning solution and the additive can be ensured.

Description

technical field [0001] The invention belongs to the technical field of electrospinning, and in particular relates to a bubble electrospinning device integrating liquid injection and oscillation. Background technique [0002] In a narrow sense, nanofibers have a diameter between 1nm and 100nm, but in a broad sense, fibers with a diameter below 1000nm are called nanofibers. Nanofibers have larger aspect ratio, surface area and porosity, and have extremely high surface activity. Therefore, nanofibers have very broad applications in textile engineering, environmental engineering, tissue engineering, biomedicine and other fields. There are various methods and equipment for producing nanofibers, and electrospinning technology is the most direct and simple method for preparing nanofibers. Under the action of electrostatic force, nanofibers are obtained by stretching and thinning. [0003] Electrospinning technology can prepare functional nanofibers such as flame retardant, antib...
