METHOD OF PRODUCING NANOFIBRES FROM POLYMER SOLUTION AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC D01D5/00 D04H3/00 

FIELD: chemistry.

SUBSTANCE: inventions relate to method of producing nanofibres from polymer solution by method of electrostatic fibre formation in electric field, created due to difference of potentials between charged electrode and opposite electrode and device for its realisation. According to method polymer solution is supplied into electric field for electrostatic fibre formation by surface of rotating charged electrode, part of whose surface is submerged into polymer solution. Simultaneously formed nanofibres under impact of electric field are displaced from rotating charged electrode to opposite electrode and then are laid on means for their laying. Nanofibres are formed on cylindrical or quadrangular, or polygonal prismatic surface of charged electrode, and opposite electrode is placed opposite free part of charged electrode, air being sucked from space between charged electrode and opposite electrode. Device for method realisation contains rotating charged electrode and opposite electrode. Charged electrode represents cylinder or quadrangular or polygonal prism, and opposite electrode is placed opposite free part of charged electrode. Polymer solution for electrostatic fibre formation by surface of rotating charged electrode is supplied into created by electrodes electric field, simultaneously formed nanofibres under impact of electric field are displaced from rotating charged electrode to opposite electrode and then are directed to means of their laying, which represents air-permeable transporter. Means for laying nanofibres can be formed by flat carrying material of nanofibres.

EFFECT: increase of productivity of nanofibres production.
