Device for production of nanofibres through electrostatic spinning of polymer composition

Abstract

The principle of the invention is the device for production of nanofibres through electrostatic spinning of polymer matrix in a spinning space, in which against each other there is positioned a collecting electrode and a spinning electrode, between which an electric field of high intensity is induced. Next to this, in the spinning space there is arranged at least one electrical device which is coupled with winding of a transformer (8), which is insulated for high voltage, while the second winding of transformer (8) is connected to the device for generating and / or evaluating of electric voltage pulses positioned outside the spinning space.

Description

technical field [0001] The invention relates to a device for the production of nanofibers by electrospinning a polymer matrix in a spinning space in which a collecting electrode and a spinning electrode are arranged against each other, between the collecting electrode and the spinning electrode A high-intensity electric field is induced between them, in which at least one electrical device is arranged. Background technique [0002] A disadvantage of all hitherto known devices for the production of nanofibers by electrospinning of liquid matrices is that the potential difference induced by the spinning and collecting electrodes (in particular due to the induction of high voltages) ) in the electrospinning field, it is impossible to place any electrical devices and power such devices. This in principle excludes the possibility of monitoring some important parameters of the electrospinning field, the polymer matrix, the conditions in the spinning space, and thus also prevents ...

Problems solved by technology

[0002] All hitherto known devices for the production of nanofibers by electrospinning of liquid matrices have the disadvantage that: In the electrospinning field induced by the potential difference (especially due to the induction of high voltage), it is impossible to place any electrical devices and power such devices

The following disadvantages lie, inter alia, in the use of a relatively large number of relatively complex elements (for example, systems for pumping polymer matrices into and out of the tank), and in the use of chemicals Longer time delay between active intervention with parameters of the polymer matrix in the distribution system and the response of these parameters during electrospinning

Moreover, when using this device, it is only possible to monitor the parameters of the polymer matrix, not the conditions in the spinning space that exert almost the same influence on the process of electrospinning
