Embodiment 1

[0032] Preparation of monocomponent helically wound fiber bundles

[0033]The spinning solution selected in this embodiment is an acetone and N-N-dimethylformamide solution containing 20% ​​by mass of polyvinylidene fluoride (PVDF). Weigh 2.0 g of PVDF first, and transfer it to the Erlenmeyer flask after weighing. Then 4.0 g of acetone and 4.0 g of N-N-dimethylformamide were added to the Erlenmeyer flask. Finally, put into a stirring magnet, and heat and magnetically stir in a 50° C. water bath for 2 hours. A uniform and transparent electrospinning precursor solution with a mass fraction of 20% can be obtained.

[0034] Use a disposable plastic straw to absorb the spinning solution and drop it into the 5ml syringe 2, ready for the electrospinning experiment. Adjust and fix the position of the first aluminum foil collector 7, set the vertical distance between the first aluminum foil collector 7 and the spinning nozzle 1 (this test is set to 35cm) and ground. The spinning no...

Embodiment 2

[0037] Preparation of multicomponent helically wound fiber bundles

[0038] Prepare three PVDF solutions with a mass fraction of 20%, one of which is added with fluorescein (the mass of fluorescein: the mass of PVDF = 1:50); the other is added with rhodamine B (the mass of rhodamine B: the mass of PVDF = 1:50) ; one serving without any substance added. Disposable plastic straws were used to drip into three syringes 2 for electrospinning, and the other conditions were the same as in Example 1. Figure 5 Optical diagram of the prepared composite nanofiber. Among them: red is excited by doped rhodamine B, yellow is excited by doped phosphor.

Abstract

The invention belongs to the field of manufacturing micro-nanofibers with an electrospinning technique, and particularly relates to an electrostatic spinning device for manufacturing heterogeneous spiral winding fiber bundles and stranded wires. The electrostatic spinning device comprises an insulation box, spinning nozzles, injection devices, an injection device fixing device, a metal connecting shaft, a first motor and a collecting device, the spinning nozzles, the injection devices, the injection device fixing device, the metal connecting shaft, the first motor and the collecting device are arranged in the insulation box, the first motor is arranged on the upper portion of the insulation box, an output shaft of the first motor is connected with the injection device fixing device through the metal connecting shaft, the injection devices are arranged on the injection device fixing device, the spinning nozzles are arranged on the injection devices respectively, the spinning nozzles are connected with the positive electrode of a high-voltage power supply, the collecting device is arranged on the lower portion of the insulation box and below the spinning nozzles, and the collecting device is connected with the negative electrode of the high-voltage power supply. The independent spinning nozzles are simultaneously operated to carry out spinning to manufacture the fiber bundles and the stranded wires, the yield of the fibers is far larger than that of a spinning device with a single spinning nozzle, and the electrostatic spinning device mainly has the advantages of manufacturing the fiber bundles with one operation and being capable of manufacturing the heterogeneous fiber bundles.

Description

Technical field: [0001] The invention belongs to the field of preparing micro-nano fibers by electrospinning technology, in particular to an electrospinning device for preparing heterogeneous helically wound fiber bundles and twisted wires. Background technique: [0002] Electrospinning is a technology that can prepare micro-nanofibers (fiber diameters between several micrometers and several nanometers) of organic polymers and inorganic compound materials on a large scale. Because of its relatively simple device, low experimental cost, convenient operation, and high spinning efficiency, it has become a research hotspot in recent years, and its potential application prospects are also very broad. For example: in biomedicine, electrospun fibers can be used to assist in the sustained release of drugs, etc.; in electronic devices, the characteristics of large specific surface area of ​​electrospun fibers can be used to prepare sensor devices. [0003] The principle and equipmen...
