Method for production of deposit or layer of nanoparticles or a layer of nanofibers from solutions or melts of polymers in electrostatic field of a high intensity, during which the produced nanoparticles or the produced nanofibers 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 nanofibers 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 nanofibers on the moving substrate material.
A device for production of a layer of nanofibres from solutions or melts of polymers comprising an active chamber, in which there are one opposite to another positioned an active electrode connected to a high voltage source and a substrate material coupled with means for initiating forward motion of the substrate material, wherein in the active chamber behind the substrate material opposite to the active electrode there is positioned at least one corona emitter of opposite polarity than the active electrode, while the trajectory of the substrate material is passing through the field of the at least one corona emitter.
