[0021] Example 1

[0022] The present invention provides a bottom-up nanofiber electrospinning device, which includes a tip metal electrode 4, a high-voltage electrostatic generator 2, a metal flat plate receiving electrode 5, a receiving curtain 10, a cylindrical liquid reservoir 7 with an open top, and The air pump 8, the air pump 8 are connected to a hollow tube made of insulating material, and the hollow tube leads to the jet hole 3. The amount of liquid added in the reservoir 7 should be higher than the top of the metal electrode 4, and the bottom surface of the reservoir 7 is equipped with The jet hole 3 connected to the air pump 8, as shown in Figure 3, there are a total of 8 jet holes 3 arranged in concentric circles, the tip metal electrode 4 is set at the center of the jet hole 3, and the tip of the metal needle of the tip metal electrode 4 is slightly extended The top of the jet hole is 1-2 mm, and the tip metal electrode 4 is connected to the high-voltage electrostatic generator 2 near the bottom surface of the liquid storage tank 7. The metal receiving electrode 5 is grounded to form a negative electrode, and an electrostatic field is formed between the tip metal electrode 4 protruding from the bottom of the reservoir 7, and the received nanofibers are under the joint action of the guide roller 11, the winding roller 12 and the unwinding roller 13. It is taken away from the deposition area and the finished product is packaged.
