Original language description

While most nanofibers are produced using electrospinning, this technique suffers from several drawbacks, such as the requirement for specialized equipment, high electrical potential, and electrically conductive targets. Consequently, recent years have seen the increasing emergence of novel strategies in generating nanofibers in a larger scale and higher throughput manner. The centrifugal spinning is simple, cheap and highly productive technology for nanofiber production. In principle, the drawing of solution filament into nanofibers using centrifugal spinning is achieved through the controlled manipulation of centrifugal force, viscoelasticity, and mass transfer characteristics of the spinning solutions. Engineering efforts of researches of the Food research institute Prague and the Czech Technical University in the field the centrifugal nozzleless spinning led to introduction of a pilot plant demonstrator NANOCENT. The main advantages of the demonstrator are lower investment cost - thanks to simpler construction compared to widely used electrospinning equipments, higher production speed, new application possibilities and easy maintenance. The centrifugal nozzleless spinning is especially suitable to produce submicron fibers from polymeric solutions in highly volatile solvents, such as chloroform, dichlormethane, tetrahydrfuran, or acetone. To date, submicron fibers have been prepared from polystyrene, polyuretane and biodegradable polyesters, such as polyhydroxybutyrate, polylactide, polycaprolactone, or polybutylensuccinate. The products are in form of 3D structures or nanofiber membranes. The nanofiber membranes and 3D constructs been tested for different applications. Filtration efficiencies for air aerosols were outstanding. Different active inserts were added to the solutions before the spinning process, such as inorganic nanoparticles, organic precursors of metal oxides, antimicrobial and wound healing compounds or photocatalytic phthalocyanines. Centrifugally spun submicron fiber membranes and 3D constructs are especially suitable for biomedical applications, such as tissue engineering, drug delivery, and wound or burn dressing.
