METHOD FOR PRODUCING POLYMERIC NANOFIBRES BY ELECTRIC OR ELECTROSTATIC SPINNING OF A POLYMER SOLUTION OR MELT, A SPINNING ELECTRODE FOR THE METHOD, AND A DEVICE FOR THE PRODUCTION OF POLYMERIC NANOFIBRES EQUIPPED WITH AT LEAST ONE SUCH SPINNING ELECTRODE

摘要

A spinning electrode for production of polymeric nanofibres by electric or electrostatic spinning of a polymer solution or melt includes a conduit for the polymer solution or melt. A spinning surface on the conduit is defined by a face of the conduit or an extension on the conduit. A screw shaft is disposed within an inner space of the conduit, wherein the screw shaft and an inner wall of the conduit form a screw conveyor. The screw shaft has a lower end that projects out from the conduit and is connected to a hub of a magnetic coupling.
