摘要：
Magnetic, electric, and radioprotector properties of hybrid nanocomposites of Fe3O4 nanoparticles with and without a shell of polyaniline (PANI), which is doped with dodecylbenzenesulfonic acid (DBSA), dispersed in polyvinylidene fluoride (PVDF) matrix have been studied. It has been found that the presence of PANI-DBSA as a separate filler in the ternary nanocomposite film, which also contains as another filler the core-shell Fe3O4/PANI-DBSA nanoparticles, facilitates dispersion of the magnetic filler due to the improvement of its compatibility with the PVDF matrix. This leads both to the decrease in coefficient of squareness of the hysteresis loop and to the increase in electromagnetic energy (EME) absorption of the nanocomposite film. [GRAPHICS] .
