Preparation and structural characterisation of magnetic NiFe2O4@ABS@Ag nanocompound with antibacterial property

The present research attempted to characterise the structural and magnetic characteristics of NiFe2O4@ABS@Ag nanoparticles (NPs) made of nickel ferrite (NiFe2O4), acrylonitrile butadiene styrene (ABS) and silver NPs (Ag NPs), this was done by employing techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy, as well as a vibrating sample magnetometer. The XRD patterns obtained indicated that following ABS and Ag NPs coating, the crystallite size (from Scherrer formula) was increased from 32 to 40 nm. It was confirmed by the magnetic measurements that the maximum magnetisation of the NiFe2O4 core was dropped when the surface was coated with ABS and Ag NPs. The antimicrobial activity of this three-component nanocomposite was tested, showing that the nanocomposite NiFe2O4@ABS@Ag could be isolated from a water solution by using a magnet.
