Abstract

The invention provides a rodlike electrospinning device and an electrospinning method. The rodlike electrospinning device is characterized by comprising a rodlike spinneret and a solution supply device which is connected with the rodlike spinneret to supply spinning solution to the rodlike spinneret, the spinning solution supplied by the solution supply device can be stored in the rodlike spinneret, and the rodlike spinneret is provided with a sawtoothed gap. The rodlike spinneret is connected with a high-voltage positive electrode, and when the voltage exceeds a critical value, various electrospinning jet flows can be generated in the sawtoothed gap. The rodlike electrospinning device is simple, the spinneret is less prone to blockage, jet flow interval uniformity, easiness in cleaning and high stability are realized, and spinning efficiency can be remarkably improved while electrospinning yield is greatly increased.

Description

technical field [0001] The invention relates to a rod-shaped electrostatic spinning device and method, belonging to the technical field of electrostatic spinning. Background technique [0002] Electrospinning is one of the most effective ways to prepare nanofiber materials. Compared with the preparation techniques of nanomaterials such as stretching method, template synthesis method, and self-assembly, electrospinning has the advantages of simple operation, short preparation process, and wide selection of materials. advantage. Compared with traditional textile fiber materials, due to their extremely small scale, nanofibrous materials have many characteristics that are difficult to exhibit at large scales, such as obvious surface and interface effects, unique small size effects, large specific surface area and extremely large size. high porosity etc. Therefore, nanofiber materials have a wider range of applications, such as air filtration, oil-water separation, medical acce...
