Embodiment Construction

[0023] The invention discloses a bubble electrostatic spinning device, which is used to solve the problem that the spinning solution of the existing bubble electrostatic spinning device is exposed to the air. The bubble electrospinning device designs the bubble generating device as a closed space, which avoids the influence of solvent volatilization on the concentration of the spinning solution and the pollution to the environment; through the mutual cooperation between the liquid inlet volume, the ventilation volume and the metal mesh, more uniform Bubbles; the design of the metal coiled liquid storage tube reduces the generation of droplets during the spinning process, making the prepared nanofibers have better morphology.

[0024] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of t...

Abstract

A bubble electrospinning device, which includes a ventilation tube, a liquid inlet tube, a metal mesh, a metal coiled liquid storage tube, a high-voltage power supply device connected to the liquid storage tube, a receiving plate facing the liquid storage tube, formed on The polymer bubbles in the liquid storage tube, the polymer bubble protrusions formed on the liquid storage tube, and the polymer jets formed outside the liquid storage tube, the vent tube is connected with one end of the liquid inlet tube and the metal mesh. In the present invention, the air bubble generating device is designed as a closed space, which avoids the influence of solvent volatilization on the concentration of the spinning solution and the pollution to the environment; secondly, the present invention produces more uniform air through the mutual cooperation between liquid intake, air flow and metal mesh. Moreover, the design of the metal winding liquid storage tube reduces the generation of droplets during the spinning process, making the prepared nanofibers have better morphology. The invention has the advantages of simple structure, convenient operation, simple control and short technological process.

Description

technical field [0001] The invention belongs to the field of spinning, in particular to a bubble electrostatic spinning device. Background technique [0002] Because nanofibers have a series of excellent characteristics such as extremely large aspect ratio, extremely high specific surface area and porosity, and extremely high surface activity, they have been widely used in textile engineering, environmental engineering, tissue engineering, biomedicine, functional composite materials and other fields. a very wide range of applications. At present, electrospinning technology is the most direct and simple method to prepare nanofibers. The core of this technology is to make the polymer solution or melt drawn from the capillary mouth to form a jet, and the charged jet is stretched under the action of electrostatic force. , thinning to obtain nanofibers. [0003] Due to the low output and easy clogging of the traditional electrospinning device, researchers have continuously impr...
