A portable electrospinning device and method of use thereof

Abstract

The invention discloses portable electrostatic spinning equipment and a using method thereof. The equipment comprises a dry battery power source, a high-voltage electrostatic generator, a gas generator and a spinning ejection device. According to the equipment, a dry battery arranged in a battery bin is used as the power source, the high-voltage electrostatic generator comprises a DC-high voltage DC inverter and a voltage regulation circuit. The voltage provided by the dry battery is increased by the DC-high voltage DC inverter to be used as spinning voltage, the airflow auxiliary spinning technology is used, a spinning nozzle is sleeved with an airflow guide pipe connected with the gas generator, and the flow direction of airflow guided into the airflow guide pipe by the gas generator is the same as the spinning jet injection direction. The equipment is low in mass, small in size and convenient to carry, can be used with no external power source, is not limited by using environment, can precisely control and adjust spinning parameters, is convenient to use and wide in application range and can better achieve orientated fiber deposition.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to a small, lightweight, portable, precisely oriented deposition, and in-situ spinning electrospinning device and a method for using the same. 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...

Problems solved by technology

As reported in the Chinese patent "A Handheld Portable Electrospinning Equipment" (201220605695.2), the traditional spinning nozzle is improved into a handheld nozzle style, so as to achieve the purpose of portability and lightness, but the device still requires an external power supply, which limits the Its use environment cannot meet the needs of practical applications; in 2012, Long Yunze et al. reported for the first time "a portable handheld electrospinning device" (201210229010.3), which uses a square battery to provide power for a high-voltage DC inverter, overcoming the The defect that the existing equipment cannot be carried around makes portability really possible, but the structure of the equipment is relatively simple, and the spinning parameters cannot be precisely controlled and adjusted, so its application is limited. At the same time, the device also has problems in the directional deposition of nanofibers. many deficiencies
