Electrostatic spinning device

Abstract

The invention discloses an electrostatic spinning device. The device comprises a driving device, a liquid inlet coupling, a liquid passing shaft, a solution tank, a rotating head, a plurality of spinning ports, an air pump, a collector, an induction rope and a high-voltage power source. The electrostatic spinning device has the advantages that the solution tank is inflated through the air pump, aspinning solution is pressed to the spinning ports by using a pressure difference, so that the solution tank accurately provides the spinning ports with the spinning solution at the same time; the induction rope has the functions of dissipating the spinning solution, inducing the spinning solution to be sprayed and effectively reducing the starting voltage when swinging along with the rotating head; when the spinning ports rotate, the spinning solution is swung into a high-voltage electric field under the action of centrifugal force to generate a jet flow, and the forming amount of the jet flow and the yield and quality of a fiber can be further adjusted and controlled by adjusting the output value of the high-voltage power source, the distance between the collector and the spinning ports,the solubility of the spinning solution, the pressure of the air pump and other electrospinning process parameters.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to an electrospinning device. Background technique [0002] Electrospinning, also known as electrospinning, is one of the main methods for producing nanofibers. It has become an important research topic in the field of materials due to its advantages of simple process and low cost. The principle of electrospinning technology is: the polymer droplets at the spinneret of the electrospinning device are placed in a high-voltage electrostatic field, and the polymer droplets will form a Taylor cone. When the electric field force is large enough, the droplets will overcome the surface tension in Taylor A jet is formed at the top of the cone, which is stretched and thinned under the action of electric field force and charge repulsion force, and finally forms nanofibers on the collecting device. [0003] Improving the yield of electrospinning has always been a hot issue in the field...
