dc.description.abstract | Polyuretan, PU, a PU/MWCNT nanokompozitní nanovlákna obojí s průměry 350 nm byly připraveny technologií elektrostatického zvlákňování z roztoku v dimethyl formamidu. SEM analýzou byla pozorována existence nanosítěk u PU/MWCNT kompozitu s průměry vláken 20-40 nm. Předpokládá se existence sekundárního elektrického pole vlivem elektricky vodivých MWCNT částic které způsobuje tento efekt růstu síťové struktury mezi vlákny. Podle našich znalostí je toto první report popisující vznik těchto nanosítěk ze syntetických polymerů. | cs |
dc.description.abstract | Polyurethane, PU, and PU/MWCNT (Multi Wall Carbon Nanotubes) nanocomosite nanofibers both with diameter 350 nm were prepared by electrospinning process from PU dimethyl formamide solutions. Appearance of nanowebs in PU/MWCNT nanofibers structure containing polyurethane fibers with diameter 20-40 nm was observed. The existence of these structures can be based on the occurrence of strong secondary electric fields which are created between individual conducting MWCNTs (distributed in PU/MWCNT nanocomposite) which start to behave as the local moving nanoelectrodes promoting creation of additional very fine nanowebs during electrospinning processes. To our knowledge, this is the first report describing nanowebs from synthetic polymers prepared by electrospinning process. | en |
