Method Of Spinning a Polymer Solution Or Melt Using Alternating Electric Voltage And a Device for Performing the Method
Original language description
The invention relates to a method of spinning a polymer solution or melt using AC voltage, which is supplied to the spinning electrode and/or to the polymer solution or melt. The spinning electrode, formed by a linear flexible structure, is during spinning wound between two driven reels , which are provided with a spiral groove on their circumference, wherein this spinning electrode is unwound from the spiral groove of one reel and at the same time is wound into the spiral groove of the second reel , wherein at least one of these reels with the part of the spinning electrode placed in its spiral groove is submerged in the polymer solution or melt stored in a reservoir , whereby the polymer solution or melt is deposited on this part of the spinning electrode and is spun from it in the space between the reels during the subsequent winding from the spiral groove of this reel into the spiral groove of the other reel. Spinning takes place around the entire circumference of the spinning electrode and the nanofibres formed, due to the action of Coulomb forces aggregate into a voluminous structure which due to the action of an electric wind driven by ions generated by corona discharges of the electric field in the vicinity of the spinning electrode moves away from the spinning electrode. The part of the spinning electrode which is currently situated in the space between the two reels and constitutes the active part of the spinning electrode , on whose surface spinning takes place, performs, as a result of winding and unwinding the spinning electrode into/from the spiral grooves of the reels in addition to the movement in the direction of its longitudinal axis, additional reciprocating sliding movement in a direction perpendicular to the longitudinal axis of the active part of the spinning electrode. In addition, the invention also relates to a device for performing the method. The patent is used on the basis of an agreement on the use of the result of a sub-project implemented within the project TN01000015 dated 12.1. 2023 concluded between the Technical University of Liberec (IČ 46747885), VUTS (IČ 46709002) and Nano Medical, s.r.o. (IČ 01780263). Contact person for negotiations: Jaroslav Beran, FS TUL, Studentská 1402/2, Liberec 1; tel. 485 353 171; jaroslav.beran@tul.cz
