Abstract

The invention relates to a device for collecting orientation nano fibre. The device comprises a roller, two metal plates, a motor and a negative high-voltage output device. The two metal plates are arranged in parallel and connected through a wire. The roller is between or above the two metal plates. When the roller is between the two metal plates, the axial direction of the roller is parallel to the length directions of the two metal plates. When the roller is above the two metal plates, the axial direction of the roller is vertical to the length directions of the two metal plates. The roller is connected with the output shaft of the motor. The two metal plates are connected with the negative high-voltage output device. The invention further relates to a method for performing electrostatic spinning by using the device for collecting the orientation nano fibre. The method comprises the following steps of: drawing electrostatic spinning jet between the two metal plates by utilizing capacitance formed between the two metal plates; and collecting orientation arrangement nano fibre by using the roller rotating at high speed. According to the device and method disclosed by the invention, the nano fibre having higher orientation degree and higher yield can be obtained.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to a device and method for collecting orienting nanofibers by parallel metal plate cylinders. Background technique [0002] In recent years, due to the convenient operation of electrospinning and a wide range of raw materials, it can be spun at room temperature; and the electrospun nanofibers have fine fineness, high porosity, large surface area, and a wide range of applications. They can be used in filter materials, sensors, tissue engineering, Drug release, etc. Therefore, electrospun nanofibers have attracted the attention of more and more researchers. Electrospinning is to bring the polymer solution or melt to thousands to tens of thousands of volts of high-voltage static electricity. The charged droplets are accelerated at the top of the Taylor cone under the action of the electric field force. When the electric field force is large enough, the polymer droplets can overcome the ...
