His work focuses on enhancing the efficiency and effectiveness of nanofiber manufacturing processes.

Latest Patents

Kotek's latest patents include a method of nanofibers production from a polymer solution using electrostatic spinning and a device for carrying out this method. The method utilizes electrostatic spinning in an electric field created by a potential difference between a charged electrode and a counter electrode. The polymer solution is supplied into the electric field using the surface of a rotating charged electrode, creating a spinning surface that attains high spinning capacity. The device designed for this method features a pivoted charged electrode, with part of its circumference immersed in the polymer solution, while the free part is positioned opposite the counter electrode.

Another significant patent is a device for perpendicular stratification of planary fibrous shapes, particularly fibrous webs. This device comprises two synchronously moving elements connected to a driving mechanism. The reciprocating moving elements are linked to their driving mechanism through a robust shaft fitted in bearings within a rigid framework. One element is connected rigidly to the shaft, while the second element is coupled via flexible joints. The driving mechanism can consist of a single driving shaft with two crank assemblies arranged with a phase shift. The flexible joints are made of flat steel springs with a width-to-thickness ratio greater than 10.
