Structure and Thermal Stability of the Polymer - Magnet Nanocomposites

It is studied a structure and thermal behavior of the hybrid polymer magnetic composites based on a high dispersive magnetite and polystyrene - butyl acrylate copolymer obtained by suspension polymerization. According to structural studies, the nanostructure of composite is formed in results of encapsulating of the magnetite particles by the polymer shells. A thermal behavior of the hybrid composite indicates the several stages of thermal decomposition process and significant reduction in the thermal stability of the copolymer matrix under the influence of magnetite.
