| dc.description.abstract | Kompozity manganozinačnatých (MnZn) feritů a polyanilínu byly připraveny oxidací anilinu s peroxydvojsíranem amonným za přítomnosti feritů. Různé reakční podmínky umožnili kontrolu tloušťky potažené vrstvy PANI, 50 # 250 nm. Komplexní magnetická permeabilitní spektra MnZn feritových částic s různou velikostí, 25-250 ?m, a jejich konpozitů s PANI, byly studovány ve frekvenčním rozsahu 1 MHz#10 GHz. Formování polymerní p-polovodivé nanovrstvy na povrchu MnZn feritových částic mění charakter frekvenční disperzi permeability. Mezifázový účinek mezi MnZn ferity a PANI nanofilmem jsou odpovědné za posun rezonanční frekvence z MHz do GHz. Tento posun silně závisí na specifické ploše mezifáze ferit-PANI a navíc, na vlastnostech PANI povlaku. | cs |
| dc.description.abstract | Core#shell composites of manganese#zinc ferrite (MnZn) and polyaniline (PANI) have been prepared by the oxidation of aniline with ammonium peroxydisulfate in the presence of ferrite. The various reaction conditions allowed controlling the thickness of PANI coating, 50#250 nm. Complex magnetic permeability spectra of MnZn ferrite of various particles sizes, 25#250 ?m, and of their composites with PANI, have been studied in the frequency range 1 MHz#10 GHz. | en |
