Novel portable electrostatic spinning device

Abstract

The invention discloses a novel portable electrostatic spinning device which comprises a host and a handheld spray gun. The host comprises a host shell, a power supply, and an air generation mechanism and a high-voltage power supply mechanism are arranged in the host shell; the handheld spray gun comprises a gun body shell, a spinning nozzle and a liquid supplying mechanism used for supplying spinning precursor liquid to the spinning nozzle, the gun body shell is provided with an air inlet and an air outlet, the air inlet is connected with an air guide pipe of the air generation mechanism, the spinning nozzle stretches out of the gun body shell from the air outlet, and the spraying end opening of the spinning nozzle coincides with the central axis of the air outlet; the power supply is electrically connected with the high-voltage power supply mechanism, the air generation mechanism and the liquid supplying mechanism, and the positive electrode of the voltage output end of the high-voltage power supply mechanism is connected with the spinning nozzle through a wire. According to the device, the spinning part and the device host are separated, use is more convenient, spinning parameters are precisely controlled and adjusted by adopting micro equipment, the application range is wide, and orientated deposition of fibers can be achieved.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to a novel hand-held electrospinning device which is portable, directional deposition, and in-situ spinning. Background technique [0002] Electrospinning is one of the simplest and most efficient methods for preparing one-dimensional micro-nano fibers. Compared with traditional nanomaterials preparation technology, it has the advantages of simple processing equipment, wide source of raw materials, low spinning cost, and large-scale preparation. In recent years, To receive extensive research reports at home and abroad. Micro-nano fibers processed by electrospinning technology have excellent characteristics such as high specific surface area, large length / diameter ratio, and unique physical and chemical properties. It shows great application potential in other fields. The principle of the electrospinning method is very simple. It is briefly described as follows: under the action of a hi...

Problems solved by technology

For example, in 2012, Long Yunze et al. reported for the first time "a portable handheld electrospinning device" (201210229010.3). This device uses a square battery to provide power for the high-voltage DC inverter, which overcomes the defect that the existing equipment cannot be carried around, making Portability is really possible, but the structure of the device is relatively simple, and there are still many deficiencies in the directional deposition of nanofibers; the Chinese patent "An Electric Field Spray Gun for Rapidly Obtaining Nanomaterials" (201320598875.7) also uses a miniature high-voltage pack for power supply, which is free from However, the problem of accurate deposition of nanofibrous materials is still unsolved.
