Polycarbonate Nanocomposites with Magnetic Fillers: Structure and Properties

In this investigation nanostructured magnetic filler modified PC composites are investigated. Nanostructured magnetic fillers were purchased (Ni0,5Zn0,5Fe2O4; CoFe2O4) and obtained by means of plasma treatment (material based on Fe2O3(Fe3O4), SiO2, CaO, Zn and other metal oxides) and sol-gel auto-combustion synthesis (Ni0,5Zn0,5Fe2O4; CoFe2O4; BaFe12O19). Most important technological parameters for the synthesis of the nanostructured ferrite fillers by sol-gel combustion synthesis were defined. Structure and certain physical characteristics of commercial and manufactured magnetic nanopowders were determined. Melt blending was applied to obtain polycarbonate based nanocomposites with various nanostructured filler weight contents: 2, 5, 10 %. Selected mechanical, rheological, thermal, calorimetric and magnetic characteristics of the manufactured nanocomposites were determined
