摘 要：A new three-component and magnetically responsive NiFe2O4@PANI@Ag nanocomposite has been fabricated by coating of nickel ferrite,NiFe2O4,nanoparticles with polyaniline（PANI） and subsequent immobilization of silver nanoparticles onto the surface of polyaniline shell.The as-prepared nanocomposite has been characterized by X-ray diffraction（XRD）,Fourier transform infrared spectroscopy（FT-IR）,scanning electron microscopy（SEM）,and vibrating sample magnetometer（VSM）.The saturation magnetization of the NiFe2O4core decreases dramatically after coating with polyaniline and silver nanoparticles,however,the nanocomposite NiFe2O4@PANI@Ag can be still separated from solution media through magnetic decantation.The antibacterial activity of the synthesized nanocomposite was studied and compared with those of naked NiFe2O4,NiFe2O4@PANI and some standard antibacterial drugs.
