| 20090148547 | DEVICE FOR PRODUCTION OF NANOFIBRES THROUGH ELECTROSTATIC SPINNING OF POLYMER SOLUTIONS - The invention relates to device for production of nanofibres through electrostatic spinning of polymer solutions comprising a spinning chamber, in which the reservoir of polymer solution is positioned, into which by a section of its circumference extends the rotating spinning electrode of elongated shape connected to one pole of high voltage source of direct current, to whose opposite pole there is connected the collecting electrode arranged in the spinning chamber against the spinning electrode, while a section of circumference of the spinning electrode extends into a polymer solution in the reservoir while the reservoir of polymer solution is divided into the inlet section, into which leads at least one inlet opening, and into which the spinning electrode extends by a section of its circumference, and the outlet section, which is provided with outlet opening. | 06-11-2009 |
| 20100028553 | METHOD AND DEVICE FOR PRODUCTION OF A LAYER OF NANOPARTICLES OR A LAYER OF NANOFIBRES FROM SOLUTIONS OR MELTS OF POLYMERS - Method for production of deposit or layer of nanoparticles or a layer of nanofibres from solutions or melts of polymers in electrostatic field of a high intensity, during which the produced nanoparticles or the produced nanofibres deposit on a substrate material passing through the active chamber, in which is positioned the active electrode. The electrostatic field for production, transfer and depositing of nanoparticles or production, transfer and depositing of nanofibres is induced between the active electrode and the substrate material, on which in the direction of its movement in front of and/or opposite to the active electrode there is applied an electric charge of opposite polarity than that of the active electrode, while an electric charge applied on the substrate material is being partially or totally consumed through depositing of nanoparticles or nanofibres on the moving substrate material. In the production device there are one opposite to another positioned the active electrode connected to a high voltage source and the substrate material coupled with means for initiating its forward motion. The substrate material is positioned in the active chamber without contact with any charged and/or grounded means while it contains quantity of electrical charge sufficient to induce electrostatic field of a high intensity between the active electrode and substrate material. | 02-04-2010 |
