Název v původním jazyce

Magnetic poly(glycidyl methacrylate)-based microspheres prepared by suspension polymerization in the presence of modified La0.75Sr0.25MnO3 nanoparticles

Popis výsledku v původním jazyce

With the aim of preparing new magnetic poly(glycidyl methacrylate) microspheres suitable for magnetic separation, La0.75Sr0.25MnO3 nanoparticles were selected as a core material. 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 distributionof 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 bythe appropriate methods, such as X-ray diffraction, FTIR spectroscopy, thermogravimetric analysis, transmission electron microscopy, light microscopy and SQUID magnetometry.
