Fabrication of Rare Earth Copolymerized Monodisperse Poly(Methyl Methacrylate) Microspheres Material

摘要

A kind of rare earth copolymerizd monodisperse Poly(methyl methacrylate) microspheres material was synthesized through dispersion polymerization. The chemical structure and chemical properties of the material were characterized by means of canning electronic microscope morphology (SEM), ultraviolet and visible spectrum (UV), dynamic laser scattering apparatus (DLS) and the thermogravimetric analysis (DTG). At the same time, the effects of different contents of monomer and rare earth content have already been investigated. SEM confirmed that the rare earth complexes have copolymerized. Meanwhile, with the content of rare earth, the microspheres show the characteristics absorption of rare earth, which will broaden the scope of application of microspheres.
