Synthesis of Monodisperse Magnetic Methacrylate Polymer Particles

Abstract

Monodisperse magnetic polymer colloids have been synthesized via a three‐step procedure and evidence for the formation of homogeneously distributed magnetite particles in the polymer matrix is presented (see Figure). Owing to their magnetic behavior and uniform particle size, these colloids are perfect candidates for the fabrication of photonic bandgap materials.

Preparation, structure, and magnetic properties of polystyrene coated by Fe3O4 nanoparticles

“…Furthermore, new methods of polymer-coated Fe 3 O 4 particle preparation from synthetic reactions have been developed [9,10]. Xu et al and Lindlar el al. reported the preparation of superparamagnetic polystyrene-iron oxide composite spheres [11,12] used in the fabrication of superparamagnetic photonic crystals. Ferromagnetic particles dispersed in a matrix of nonmagnetic material may show great magnetoresistance and therefore, which can be applied in magnetic recording heads.…”

Selective preparation of novel fluoroalkyl end-capped co-oligomeric nanocomposite-encapsulated magnetites and magnetite-adsorbing co-oligomeric nanoparticles

“…So far, numerous synthetic and natural polymers have been used to obtain stable colloidal dispersions of magnetic nanoparticles by coating and encapsulating the particles. [22][23][24][25][26][27][28][29][30][31] It is well known that fluorinated surfactants have excellent surface characteristics, including oleophobicity and hydrophobicity, neither of which can be achieved with corresponding nonfluorinated polymers. 32 Thus, it is of particular interest to develop new, tailored magnetic fluorinated polymer colloids that possess not only good dispersibility in various solvents but also the unique active surface characteristics imparted by fluorine.…”

Homogeneously distributed magnetite in the polystyrene spherical particles using the miniemulsion polymerization

“…The preparation of the magnetic copolymer particles of 400-800 nm in diameter [27] was reported using methylmethacrylate and glycidyl methacrylate. In addition, the chemical modification using ethylene diamine to obtain internal anchor groups and the generation of magnetic nanoparticles by impregnation and subsequent hydrolysis of Fe 3+ / Fe 2+ chloride in the methacrylate matrix via layer-by-layer deposition technique were employed.…”
