Abstract

The synthesis and characterization of MnFe2O4 incorporated in magnetic polyvinylamine (PVAm) nanoparticles was reported. N-vinylformamide was used as a monomer, and 2,2́-Azobis was used as an initiator for the polymerization reaction of N-vinylformamide. Crosslinked PVAm nanoparticles were produced and fabricated by inverse microemulsion polymerization of monomer with crosslinker. MnCl₂ and FeCl₃ were dissolved in 25 mL of deoxygenated PVAm nanoparticle suspension. The solution was stirred for 2 h at room temperature and the solution of PVAm nanoparticles containing MnCl₂ and FeCl₃ was transferred to a centrifuge tube and centrifuged for 30 min at 15,000 rpm. Transmission electron microscopy (TEM) images of PVAm/MnFe₂O₄ nanoparticles at different time intervals were obtained after aging at 90 °C. The saturation magnetization of PVAm/MnFe2O4 particles with a 1:2 Mn:Fe ratio was ~ 40 emu/g of MnFe2O4.
