Problems solved by technology

However, these collection methods can usually only obtain electrospun structures of a single shape, or the structures of the receiving parts are complex and difficult to manufacture, and the patterning is realized by geometric methods and mechanical structures. The graphics are not rich enough and the controllability is not strong.

Embodiment 1

[0025] In this example, see figure 1 with figure 2 , an electrospinning device, which is composed of a micropump 4, a liquid supply extrusion device 1, a receiving part 2 and a high-voltage power supply 3, and a device with a The fixed-shaped strong soft magnetic plate makes the surface area part of the receiving part 2 facing the liquid supply extrusion device 1 and corresponding to the area glued with the strong soft magnetic plate form a set area for collecting fiber aggregates, and adjust the liquid supply extrusion The distance between the outlet of the feeding nozzle of the device 1 and the receiving part 2 is 200-400mm, the feeding nozzle of the liquid feeding extrusion device 1 is connected to the positive pole of the power supply, and the receiving part 2 with a strong soft magnetic plate of a certain shape is connected to the negative pole of the power supply , control the high-voltage power supply 3 to provide a voltage of 10-20kv and adjust the size of the voltag...

Embodiment 2

[0033] This embodiment is basically the same as Embodiment 1, especially in that:

[0034] In this example, see image 3 , an electrospinning patterned collection method, it comprises the following steps:

[0035] a. This step is identical with embodiment one;

[0036] b. Stick the strong soft magnetic plate cut into a five-pointed star on the surface of the receiving part 2 facing away from the liquid supply extrusion device 1, so that the area of ​​the receiving part 2 corresponding to the strong soft magnetic plate glued with the five-pointed star is formed to collect For the five-pointed star setting area of ​​the fiber aggregate, adjust the distance between the liquid supply extrusion device 1 and the receiving part 2 to receive the film to 200mm, connect the supply nozzle of the liquid supply extrusion device 1 to the positive pole of the high-voltage power supply 3, and place the sticky The receiving part 2 of the pentagram-shaped strong soft magnetic plate is conne...

Embodiment 3

[0040] This embodiment is basically the same as the previous embodiment, and the special features are:

[0041] In this example, see Figure 4 , an electrospinning patterned collection method, it comprises the following steps:

[0042] a. This step is identical with embodiment one;

[0043] b. Take the prepared gelatin-sodium alginate bone scaffold, which has high porosity and regular pores, and put the receiving part 2, which has the same shape as the planar projection shape of the gelatin-sodium alginate bone scaffold, with a strong soft magnetic plate. Under the gelatin-sodium alginate bone bracket, a strong soft magnetic plate cut into a set shape is glued to the surface of the receiving part 2 on the side of the liquid supply extrusion device 1, so that the corresponding shape is glued. The area of ​​the receiving part 2 of the strong soft magnetic plate forms a set area for collecting the set shape of the fiber aggregate, adjust the distance between the liquid supply...

Abstract

The invention discloses an electrostatic spinning patterning collection method and an electrostatic spinning apparatus. Based on a conventional electrospinning technical method, through a composite electrospinning material and changing of a receiving apparatus, a novel orderly controllable receiving apparatus and a control method are developed, and an orderly electrospinning fiber structure body with a needed pattern shape is prepared through preparing an organic / inorganic composite material electrostatic spinning liquid with a certain ratio and changing a carrying portion. The method and the apparatus are high in controllability, fibers are directionally consistent and orderly, the electrospinning collection is more flexible, the control method is simpler, and the receiving patterning effect is better. According to the invention, obtained electrospinning fiber films in any shapes can also be applied to such biomedical fields as magnetic medicament transportation, cell marking, biosensors and the like, and the application of electrospinning in industries especially bio-manufacturing is expanded.

Description

technical field [0001] The invention relates to a material forming method and device, in particular to a 3D forming preparation method and device, which are applied in the technical fields of electrospinning and biomanufacturing. Background technique [0002] Magnetic nanomaterials are a kind of nanomaterials, generally referring to magnetic materials with particle sizes between 0-100nm. Magnetic materials mainly refer to substances composed of iron, nickel, cobalt and their alloys that can directly or indirectly generate magnetism. In addition to the surface effects, quantum size effects, and volume effects that are unique to general nanomaterials, they also present some unique and excellent properties. Physical properties, such as superparamagnetism, high saturation magnetization, biocompatibility, low toxicity, etc. Superparamagnetism is a very unique property in the paramagnetism of magnetic nanomaterials, which means that at room temperature, when nanoparticles When th...
