摘要：
The composites of Fe3O4 nanoparticles and polymers have wide ranges of application. This paper reported the Ni3Si/Fe3O4@polyvinylidene fluoride (PVDF) magnetic composite with different Fe3O4 nanoparticles content based on Ni3Si template, which exhibits the coexistence of low-field hysteresis and high-field paramagnetic. The magnetic properties of Ni3Si/Fe3O4@PVDF composites originate from the ferromagnetic competition between Fe3O4 nanoparticles and Ni3Si template. At low temperatures, both Fe3O4 nanoparticles and Ni3Si template exhibit ferromagnetism. The higher the nanoparticles content, the more pronounced the competition between them, and the weaker the ferromagnetism of Ni3Si/Fe3O4@PVDF composites. However, the magnetic moment disorder of both the Fe3O4 nanoparticles and Ni3Si templates intensify with the increasing temperature. At 300 K, the ferromagnetism of lamellar Ni3Si template almost disappears completely, and the magnetic properties of Ni3Si/Fe3O4@PVDF composites are enhanced with the increasing Fe3O4 nanoparticles content. Therefore, the magnetic property regulation of Ni3Si/Fe3O4@PVDF composites can be achieved by adjusting Fe3O4 nano-particles content.
