20.500.12556/DKUM-60157 Monolithic magneto-optical nanocomposites of barium hexaferrite platelets in PMMA The incorporation of magnetic barium hexaferrite nanoparticles in a transparent polymer matrix of poly(methyl methacrylate) (PMMA) is reported for the first time. The barium hexaferrite nanoplatelets doped with Sc3+, i.e., BaSc0.5Fe11.5O12 (BaHF), having diameters in the range 20 to 130 nm and thicknesses of approximately 5 nm, are synthesized hydrothermally and stabilized in 1-butanol with dodecylbenzenesulfonic acid. This method enables the preparation of monolithic nanocomposites by admixing the BaHF suspension into a liquid monomer, followed by in-situ, bulk free-radical polymerization. The PMMA retains its transparency for loadings of BaHF nanoparticles up to 0.27 wt.%, meaning that magnetically and optically anisotropic, monolithic nanocomposites can be synthesized when the polymerization is carried out in a magnetic field. The excellent dispersion of the magnetic nanoparticles, coupled with a reasonable control over the magnetic properties achieved in this investigation, is encouraging for the magneto-optical applications of these materials. polymer composites nanoparticles polymethyl methacrylate PMMA polimerni kompoziti nanodelci polimetil metakrilat PMMA true false true Angleški jezik Slovenski jezik Znanstveno delo 2016-06-09 03:15:13 2017-06-23 11:47:43 2022-06-22 03:06:06 2019-07-11 11:37:13 2015 0 0 str. 1-8 Letn. 5 jun. 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2045-2322 66 18727432 18777878 10.1038/srep11395 2045-2322 URN:SI:UM:DK:JN0COY4B Scientific_Reports_2015_Ferk_et_al._Monolithic_Magneto-Optical_Nanocomposites_of_Barium_Hexaferrite_Platelets_in_PMMA.pdf Scientific_Reports_2015_Ferk_et_al._Monolithic_Magneto-Optical_Nanocomposites_of_Barium_Hexaferrite_Platelets_in_PMMA.pdf 1 9CE65BC25653809D3A2883C3CA065B7B 7de98d9223012d1d90de6c6348a5f8ecee065a672695a51d888a3ddf628e2a7f 4aa80ef4-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113028 http://www.nature.com/articles/srep11395 1 https://dk.um.si/Dokument.php?lang=slv&id=93972 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
