Popis výsledku v původním jazyce

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, dichlormethan, tetrahydrfuran, or acetone. To date, submicron fibers have been prepared from polystyrene, polyuretane and biodegradable polyesters, such as polyhydroxybutyrate, polylactid, polycaprolactone, or polybutylensuccinate in form of unique self-supporting membranes and 3D constructs. The nanofiber membranes and 3D constructs been tested for different applications. Filtration efficiencies for water solutions and aerosols in air were evaluated. 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. Sintering or hydrothermal treatment can be subsequently carried out to remove the polymeric material and transfer the organic precursors to metal oxides, such as Si02, or Zn02 and Ti02, to obtain inorganic nanofibers. Centrifugally spun submicron fiber membranes are especially suitable for biomedical applications, such as tissue engineering, drug delivery, and wound or burn dressing.
