The invention discloses a linear electrode static spinning device having sharp teeth, and belongs to the technical field of electrically spun nanometer fibers. The linear electrode static spinning device having sharp teeth comprises an electrode, a power supply and a collecting device arranged corresponding to the electrode. The power supply is electrically connected to the electrode and the collecting device. One side, facing to the collecting device, of the electrode is provided with a plurality of uniform sharp teeth, all the sharp teeth has tips having intervals being equal to that of the collecting device, and a jet flow electric field is formed between the electrode and the collecting device after the power supply is started. The electrode having sharp teeth is employed by the linear electrode static spinning device having the sharp teeth, the teeth tips can form a tip charge aggregation effect which can easily induce to spin, the sizes and the intervals of the sharp teeth of the electrode are uniform, jet flow field are uniformly distributed, uniform jet flows can be generated, nanometer fibers can be uniformly deposited, and the electrode is simple in structure, convenient to machine and suitable for mass production.

Description

technical field [0001] The invention is used in the technical field of electrospinning nanofibers, and in particular relates to a linear electrode electrospinning device with sharp teeth. Background technique [0002] Electrospinning technology is the most commonly used and most economical method for producing nanofibers, and has achieved spinning of various materials in solution or molten state. The principle is: under the action of a high-voltage electrostatic generator, a high-voltage electrostatic field is formed between the spinning jet device and the nanofiber receiving device; the spinning solution or melt forms a jet under the action of the electric field, and the jet becomes thinner under the pull of the electric field , bending, cleaving into finer forms, and finally depositing on a collection device to form nanofibers. [0003] Because of its high specific surface area, nanofibers have excellent physical and chemical properties, and have great application advanta...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a linear electrode electrospinning device with canines. Using the principle of tip charge accumulation effect, a spinning electrode with canines is designed, and the canines of the spinning electrode have good uniformity. Therefore, the electric field is evenly distributed, and it is easy to obtain uniform nanofibers. At the same time, this process belongs to non-needle spinning, which avoids the problem of nozzle blockage in needle spinning.
