Synthesis of nano-sized magnetic colloidal particles from ferrous salts and hydroxylated poly(butyl methacrylate-b-glycidyl methacrylate)

Abstract
Poly(butyl methacrylate-b-glycidyl methacrylate) is used to prepare magnetic nanoparticles from ferrous salts. The structural identification of synthesized colloidal particles and bulk magnetite is performed via X-ray diffraction. Magnetic hysteresis studies show that the obtained microspheres are specified as soft magnetic materials. Microspheres have a ferrite core and a polymer shell. The size and size dispersion of the microspheres decrease with the total concentration of ferrous salts.
