Electrostatic spinning nozzle with cylindrical surface and spaced hexagon arrays and electrostatic spinning method

Abstract

The invention discloses an electrostatic spinning nozzle with a cylindrical surface and spaced hexagon arrays and an electrostatic spinning method. The electrostatic spinning nozzle comprises a body, and the body is provided with the cylindrical surface at the top and at least two output structures. Each output structure is in linear array arrangement along the axial direction of the cylindrical surface, and the following output structure is symmetrical to the previous output structure in the axial direction of the cylindrical surface, and is spaced from the previous output structure by a certain distance. Each output structure comprises six connection holes formed in the cylindrical surface, each connection hole is connected with a needle-type nozzle, and the needle-type nozzles extend along the normal direction of the cylindrical surface and are equal in height. Projections of the connection holes in the same output structure on the horizontal surface are located at end points of the corresponding equilateral hexagon respectively. One vertex angles of every two adjacent equilateral hexagons are opposite to each other. The needle-type nozzles have small differences in electric field intensity, and tip electric fields of the nozzles are uniform. The electrostatic spinning nozzle and the electrostatic spinning method can be applied to electrostatic spinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning nozzle and an electrospinning method with cylindrical hexagonal spaced arrays. Background technique [0002] The invention patent with the application number 200910031948.2 discloses an array multi-nozzle electrospinning equipment, which uses multiple nozzles arranged in a linear rectangular array on the plane for spinning, which can realize mass production of electrospun fiber membrane materials. [0003] However, after a long period of use, technicians found that when the nozzles are arranged in an array on a plane, the electric fields at the tips of the nozzles will affect and interfere with each other, resulting in large differences in the electric fields between different nozzles, resulting in uneven spinning. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to provide an electrospinning nozzle...
