Method for manufacturing polymer nanofiber by electrospinning polymer solution or melt, spinning electrode for carrying out the method, and apparatus for manufacturing polymer nanofiber with at least one such spinning electrode

摘要

The present invention relates to a spinning electrode for producing polymer nanofibers by electrospinning of a polymer solution or melt, comprising an inlet pipe (2) of the polymer solution or melt terminating at its upper surface (3). (1), so that at least part of the mouth (20) on the upper surface of the inlet pipe (2) of the polymer solution or melt is directed downward below the mouth (20). A rounded spinning surface (4) is formed, whereby the spinning surface (4) continues as a collecting surface (6) on the outer surface of the polymer solution or melt inlet pipe (2). Regarding 1). The invention also relates to an apparatus for producing nanofibers by electrospinning a polymer solution or melt, comprising at least one spinning electrode (1) according to the invention. In addition, the present invention relates to a method for producing nanofibers by electrospinning polymer solutions or melts based on the use of a spinning electrode according to the present invention.
