Abstract
The invention discloses a simple and efficient electrostatic spinning device for preparing directional nanofibers, and belongs to the field of electrostatic spinning. The simple and efficient electrostatic spinning device mainly comprises a high-voltage electrostatic generator, a parallel grille collector communicated on the bottom of the device, a needle tube used for storing electrostatic spinning solution, a direct-current speed regulator, a driving motor and an insulation breaker. The positive pole of the high-voltage electrostatic generator is connected with a needle head of the needle tube through a copper sheet and an electric brush below a needle tube fixing disc, and the negative pole of the high-voltage electrostatic generator is connected with the collector. The rotation speed of the driving motor is controlled through regulating voltage of the direct-current speed regulator so that the needle tube connected with the driving motor is driven to rotate horizontally at a certain rotation speed. High-voltage electrostatic drives the polymer spinning solution to form the nanofibers, centrifugal force produced by circular motion of the needle tube drives the nanofibers to be attached to the grounded parallel grille collector, and therefore directionally aligned nanofiber membranes are obtained.
