Abstract
Objectives: Manganese Ferrite nanoparticles are a current hot topic in medicine and pharmaceutics. In the current investigation, MnFe2 O4 NPs/ABS Nanocomposite have been successfully synthesized via Co-precipitation method process. Methods/Statistical Analysis: Manganese Ferrite nanoparticles (MnFe2 O4 (MF) NPs) were synthesized by the Co-precipitation method then annealing at 400°C. A nanocomposite of MnFe2 O4 with acrylonitrile (A) butadiene (B) styrene (S) (MF/ABS) was prepared. Scanning electron microscopy (SEM), energy dispersive analysis X-ray (EDAX) and transition electron microscopy (TEM) were used to characterize the morphology and particle size of the MF NPs and MF/ ABS nanocomposite. Findings: The nano-powders obtained have a spherical structure and particle size of approximately 8 nm. The optical properties were studied by UV-Vis spectroscopy to estimate the band gap of the MF NPs and MF/ ABS nanocomposite. The magnetic properties of the MF NPs and MF/ABS nanocomposite were investigated using a vibrating sample magnetometer (VSM). We found that the MF NPs exhibit a superparamagnetic behaviour. The saturation magnetization Ms (8.4277E-3 emu/g) and coercivity Hci (91.208 G) at room temperature for the MF/ABS nanocomposites were higher than Ms and Hci for the MF NPs. The exchange bias effect appears in the MF/ABS nanocomposite. The thermal results show that the glass transition temperature (Tg) of the MF/ABS nanocomposites is 108.54 ºC. Application/ Improvements: Adding 10% of MF NPs to ABS polymer enhance ABS thermal properties and change ABS magnetic properties. Keywords: Exchange Bias Effect, Nanocomposite, Superparamagnetic, Thermal Stability, ABS
Highlights
Magnetic nanoparticles are a current hot topic in medicine and pharmaceutics[1]
We demonstrate the presence of Mn and Fe, the contents of which amounted to 34.87% and 18.73%, respectively
A Si Kα X-ray was produced from the silicon detector crystal; the energy measured for the incoming X-ray was reduced by the magnitude of the Si Kα X-ray, i.e., 1.74 keV, and a Si escape peak was detected in the energy dispersive analysis X-ray (EDAX) spectrum
Summary
Nanoparticles promise matchless improvements for numerous sectors, such as medicine, energy, biosensors, and materials[2,3,4,5]. These materials have a very wide range of applications due to their unique combination of high magnetization and paramagnetic behaviour. When multiple layers of a ferromagnet connect with an antiferromagnet, a shift of the hysteresis loop over the magnetic field axis called exchange bias can happen. This phenomenon is observed to enhance the coercivity (Hci)[12]
