The course is focused on the state-of-art nanofiber production technologies presented to students through practical projects supported by the theoretical background. The course covers the key technologies for production of nanofibers and nanofiber structures. The course projects will be solved in teams of students and will include the design of a spinning device, the preparation of production documentation, assembly and testing of the spinning device in a real polymer nanofiber production facility. Verification of the functionality of the developed design will also include material evaluation of the produced nanofiber material from the perspective of its use in medical and textile applications. By completing the course, students will gain not only theoretical knowledge in the field of polymer nanofiber production technologies, but also practical experience covering the entire development process, i.e., equipment design, assembly, operation of spinning equipment during operation, and evaluation of the nanofiber materials produced using the designed spinning equipment according to the project specifications.
