Electrostatic spinning device for batch preparation of orderly nanofibers

Abstract

The invention discloses an electrostatic spinning device for multi-jet batch preparation of orderly nanofibers. The device comprises a quantitative liquid supply pump, a liquid guiding pipe, a liquid inlet plate, a nozzle plate, an insulating sleeve, an upper porous plate, a lower porous plate, a roller, a support, a rotating shaft, a coupler, a motor, a pinpoint ground electrode, an X-Y moving platform and a high-voltage power supply. According to the device, multiple jets are generated through multiple nozzles to increase yield; the whipping range of jets is restrained by the electrode which is assisted by the upper and lower porous plates, so that the fibers can be easily subjected to orderly controlled deposition; linkage of rotation and translation can be generated due to the X-Y moving platform and roller collection method; the pinpoint ground electrode is used for focusing nanofiber deposition to carry out accurate and orderly winding collection of nanofibers; the runner optimizing design is introduced into the multiple jets, so that the flowrate at each nozzle is uniform, and the uniformity of the nanofiber diameter can be improved; the nozzles are coated with an insulating material and are electrically insulated, so that the electrostatic inhibiting effect among the nozzles can be reduced, and the intensities of electric fields at the nozzles can be balanced.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an electrostatic spinning device for preparing ordered nanofibers in batches with multiple jets. Background technique [0002] Nanomaterials have small size effect, surface and interface effect, quantum size and tunnel effect that macroscopic substances do not have. These characteristics make nanomaterials have many physical and chemical properties different from traditional materials, such as UV resistance, high strength and toughness, good The electrostatic shielding effect, antibacterial and adsorption capabilities, etc., have advantages that traditional materials do not have. Electrospinning is a simple way to manufacture micro-nano-sized fibers. Compared with other methods, such as template polymerization, vapor deposition, hydrothermal and solvothermal synthesis, and solid-phase mechanochemical synthesis, it is more effective. The advantages of simple device, simple prin...

Problems solved by technology

However, the devices using these methods are all based on single-nozzle electrospinning devices to collect nanofibers, and there are still relatively few devices for preparing ordered nanofibers in batches. For the industrial production of ordered nanofibers, batch preparation is the key necessary conditions
