Embodiment 1
[0051] Such as Figure 1~5 As shown, a device for producing polymer nanofibers at least includes a liquid tank 2, a receiving device 7, and several first electrodes 3 and several second electrodes 4 forming potential differences.
[0052] The receiving device 7 comprises a substrate and several transport components. Such as figure 1 As shown, the conveying assemblies at both ends of the substrate include a first conveying assembly 61 and a second conveying assembly 62 . For example, both ends of the substrate are controlled by at least two pairs of unpowered rollers and are moved to receive nanofibers sprayed from the second electrode to form a nanofiber layer.
[0053] The moving state of the substrate includes movement-related parameters such as static time, moving speed, and moving time.
[0054] Preferably, several first electrodes 3 are arranged in the electrode chamber 1 . The arrangement of the plurality of first electrodes 3 is not limited, and may be arranged in a...
Embodiment 2
[0095] This embodiment is a further elaboration of Embodiment 1, and the repeated content will not be repeated.
[0096] The present invention also provides a method for producing polymer nanofibers, the method at least comprising:
[0097] The substrate in the receiving device is arranged in the manner of passing through the electric field between several first electrodes 3 and several second electrodes 4, or the substrate in the receiving device is arranged in the electric field, at least one second electrode 4 is connected with The liquid tank 2 dips in the polymer solution in a relatively moving manner and spins to the receiving device 7 based on the action of an electric field to form a nanofiber layer.
[0098] The second electrode 4 dips in the polymer solution in an intermittent energized manner.
[0099] When the second electrode 4 moves to contact with the polymer solution in the liquid tank 2 , the second electrode 4 is powered off, and when the second electrode 4 ...
