In order to improve their compatibility with PGMA, the surface of the nanoparticles was treated with penta(methylethylene glycol) phosphate methacrylate as a stabilizer. Subsequently, the nanoparticles were encapsulated by the suspension polymerization of glycidyl methacrylate resulting in a relatively homogeneous distribution of La0.75Sr0.25MnO3 nanoparticle aggregates inside the polymer microspheres. Both PMGPMA-coated La0.75Sr0.25MnO3 nanoparticles and magnetic PGMA microspheres were characterized in terms of morphology, particle size, composition and magnetic properties by the appropriate methods, such as X-ray diffraction, FTIR spectroscopy, thermogravimetric analysis, transmission electron microscopy, light microscopy and SQUID magnetometry.
