Polymers are generally electrically non-conductive and non-magnetic materials. Natural Halloyzite nanotubes (HNT) modified with iron oxide nanoparticles were used to improve the mechanical properties of the polymeric material. When researching such nanocomposites, it is important to know the concentration of magnetic nanoparticles and their magnetic properties. It has been found that modifying HNT with iron nanoparticles produces a superparamagnetic substance with scalable saturation magnetization. The resulting polymer \/ modified HTN composite material can be classified as a magnetically soft substance and the presence of magnetized HNT clearly has a positive effect on its mechanical properties.<br \/>\nThe results were achieved in cooperation with the following workplaces:<br \/>\n\u2022 Department of Plastics, Rubber and Fibers (\u00daPSP FCFT) in Bratislava<br \/>\n\u2022 Regional Center for Advanced Technologies and Materials, \u010cesk\u00e9 Bud\u011bjovice, Czech Republic<br \/>\n\u2022 Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic, Prague, Czech Republic<\/span><\/p>\n<p><span class=\"tlid-translation translation\" lang=\"en\"><br \/>\n<strong>Related projects:<\/strong><br \/>\n\u2022 VEGA 2\/0152\/13<br \/>\n<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong><span class=\"tlid-translation translation\" lang=\"en\">Publication:<\/span><\/strong><\/p>\n<p>KHUNOV\u00c1, V. &#8211; \u0160AFA\u0158\u00cdK, I. &#8211; <u>\u0160KR\u00c1TEK, Martin<\/u> &#8211; KELNAR, I. &#8211; TOMANOV\u00c1, K.
