His work focuses on methods and devices for producing linear fibrous formations with unique properties.

Latest Patents

Chvojka's latest patents include a "Linear fibrous formation with a coating of polymeric nanofibers enveloping a supporting linear formation constituting a core, a method and a device for producing it." This invention provides a method, system, and resulting linear fibrous formation where a supporting linear formation defines a core transported through a spinning chamber. The coating of polymeric nanofibers envelops the supporting linear formation, created from a hollow electrically neutral nanofibrous plume generated in a spinning space above a spinning electrode during spinning by AC electric voltage.

Another significant patent is the "Method for production of polymeric nanofibers by spinning of solution or melt of polymer in electric field." This invention relates to a method for producing polymeric nanofibers through the action of an electric field on a polymer solution or melt. The electric field is created alternately between the spinning electrode and ions of air or gas, resulting in the formation of polymeric nanofibers that cluster together under electrostatic forces into a linear formation.
