Abstract

Disclosed in the invention is an electrostatic spinning device comprising a fixed plate 6. A regulation motor 3 is fixed on the fixed plate 6; a rotating shaft 4 is installed at the output terminal of the regulation motor 3 and passes through a circular hole in the middle of the fixed plate 6; and a driving belt wheel 9 sleeves the rotating shaft 4. A bearing 14 is arranged at the left side of the fixed plate 6; a driven belt wheel 13 is fixed on the outer ring of the bearing 14; and transmission between the driving belt wheel 9 and the driven belt wheel 13 is realized by a belt 8. A liquid delivering device is connected to the upper end of the inner ring of the bearing 14; a connector 16 is connected to the lower end of the inner ring of the bearing 14 and is connected with a spinning needle head 12; the spinning needle head 12 is connected with a high-voltage generator 18; and a roller collection unit 19 is arranged right below the spinning needle head 12 and is connected with a ground electrode. According to the invention, a three-dimensional porous fiber membrane support prepared by the device has advantages of high porosity, large aperture, and high mutual connectivity; and cell entrance and cell proliferation as well as conveying and discharging nutrient solution and metabolic products can be realized well.

Description

technical field [0001] The invention belongs to the field of material processing, and relates to an electrostatic spinning device. Background technique [0002] In recent years, based on the simplicity of electrospinning equipment, a wide variety of available materials, the convenience of preparing multi-component composite materials, and the excellent performance of the prepared nanofibers with large specific surface area and good internal connectivity, it has been used in biomedicine and drug control. Release systems, compound modification of materials, filtration and protection, tissue engineering and other fields have received extensive attention and applications. However, due to the dense packing of the prepared nanofibers, the pore size is small and the porosity is low, which limits its application in the fields of adsorption filtration, drug delivery, tissue engineering and biomedicine. Strictly speaking, the tissue engineering scaffold produced by electrospinning te...

Problems solved by technology

However, there is still no simple and easy-to-implement technology to prepare fibrous membranes with helical structures.

For the preparation of fibrous membranes with helical structure according to the difference in material conductivity or elongation at break, there is a disadvantage that the available materials are limited, and only composite component fiber membranes can be prepared

For the preparation of micro / nanofibers with twisted helical structures through the improvement of typical electrospinning devices, there are disadvantages such as complex devices, cumbersome operations and long post-processing time.
