METHOD FOR PRODUCTION OF POLYMERIC NANOFIBERS AND LINEAR FORMATION FROM POLYMERIC NANOFIBERS PREPARED BY THIS METHOD Russian patent published in 2018 - IPC D01D5/00 D04H1/728 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for producing polymer nanofibers, in which the production of polymer nanofibers is carried out by the action of an electric field on a polymer solution or melt that is located on the surface of a spinning electrode, about which electrostatic field is created alternately between spinning electrode (1), which is supplied with alternating voltage and ions (30, 31) of air and/or gas generated and/or supplied into the surrounding space, for electrostatic spinning of the fiber without the use of a counter electrode, and depending on the phase of the alternating voltage on spinning electrode (1), polymeric nanofibres with an opposite electric charge and/or sections with an opposite electric charge are formed, which after their occurrence under the action of electrostatic forces are grouped, forming a linear system in the form of a miniature tow or band, which freely moves in space from spinning electrode (1) in the direction of the electric field gradient. Further, the invention relates to a linear system of polymer nanofibres created using this method.

EFFECT: method for producing polymer nanofibres and a linear system of polymeric nanofibres obtained by this method are proposed.
