Iron nanoparticles (Fe(0)), were encapsulated into polymethyl methacrylate (PMMA), by means of emulsion polymerization techniques in a semicontinuous process. The final average diameter of the composite particle was calculated until three times of average particle of iron particles and were stabilized with a non-ionic surfactant. They were then characterized by scanning electron microscopy and dynamic light scattering. Their magnetic properties were determined by parallel field vibrating-sample magnetometry method. The results indicated that the magnetic properties are a function of polymer concentration in the nanocomposite particle.
Graphical abstractNanoparticles of Fe(0) were encapsulated with different amount of PMMA. The magnetization properties were a function of final average diameter of composite particle.Figure optionsDownload full-size imageDownload high-quality image (70 K)Download as PowerPoint slideResearch highlights► The magnetic polymers exhibit a fast and very strong response to external magnetic fields. ► Particles of Fe(0) were encapsulated with different quantity of polymethyl methacrylate. ► The magnetization values of the Fe(0) nanoparticles naked and encapsulated were largest than those reported for magnetite.
