Problems solved by technology

[0003] Studies have shown that in addition to factors such as tip potential, fluid viscosity, conductivity, receiving distance and surface tension, the diameter of the bubble also has a certain impact on the quality of nanospinning. If the diameter of the bubble is too large or too small, the spinning process instability

Abstract

The invention discloses a bubble electrostatic spinning device which comprises a liquid storage tank, a high-voltage electrostatic generator, an air pump, a receiving electrode plate and a bore control device. An air spraying pipe is arranged at the bottom of the liquid storage tank and connected to the air pump through an air guide pipe, and the bore control device is used for controlling the sizes of bubbles, provided with a limiting port and arranged above the liquid storage tank. The diameters of the generated bubbles are controlled by the aid of the limiting port on the bore control device, stability of nano spinning is improved, and the diameter of the limiting port can be adjusted according to the property of solution or melt in the liquid storage tank.

Description

technical field [0001] The invention belongs to the field of electrospinning, and in particular relates to a bubble electrostatic spinning device capable of changing the diameter of bubbles. Background technique [0002] Nanofibers have the characteristics of ultra-high specific surface area, extremely large aspect ratio, high surface activity, superior mechanical properties (high strength and high toughness), etc., and have very broad application prospects in different fields such as textile engineering, environmental engineering, and biotechnology. . Compared with the traditional electrospinning technology, the bubble electrospinning technology has greater advantages, such as improving the spinning efficiency and output of nanofibers. [0003] Studies have shown that in addition to factors such as tip potential, fluid viscosity, conductivity, receiving distance and surface tension, the diameter of the bubble also has a certain impact on the quality of nanospinning. If the...
