“…By far, there are two main approaches for the preparation of the polymer-based magnetic nanocomposites: physical mixing and in situ polymerization. In the first approach, the magnetic nanoparticles were physically mixed into polymeric matrices after being surface-modified with polymers [2][3][4][5][6][7]. The strategy is suitable for the largescale industrial manufacturing, however, the uniform dispersion of the magnetic nanoparticles in the polymeric matrices could not be guaranteed [2].…”

Abstract. Organo-modified ferroferric oxide superparamagnetic nanoparticles, synthesized by the coprecipitation of superparamagnetic nanoparticles in presence of oleic acid (OA), were incorporated in polystyrene (PS) by the facile in situ bulk radical polymerization by using 2,2-azobisisobutyronitrile (AIBN) as initiator. The transmission electron microscopy (TEM) analysis of the resultant uniform ferroferric oxide/polystyrene superparamagnetic nanocomposite (Fe3O4/PS) showed that the superparamagnetic nanoparticles had been dispersed homogeneously in the polymer matrix due to the surface grafted polystyrene, confirmed by Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis (TGA). The superparamagnetic property of the Fe3O4/PS nanocomposite was testified by the vibrating sample magnetometer (VSM) analysis. The strategy developed is expected to be applied for the large-scale industrial manufacturing of the superparamagnetic polymer nanocomposite.

“…The samples with 8 phr were immersed in hot water (80 1C) during 4 h. The ferrofluid (14% weight of Fe 3 O 4 ) was synthesized following a procedure reported previously [5]. The formulations used to obtain the magneto-polymeric nanocomposite were: PVC 100, DOP 140, Ca/Zn 4, ATES 8 and different amounts of ferrofluid 5, 10, 20, 30, 40, 50 phr.…”

“…As an example, the synthesis of magnetite particles of iron (III) chloride for the incorporation into silicone elastomers was considered by Evans et al [13]. Especially for the PVC polymer system the only described method is the preparation and incorporation of a ferrofluid with DOP (dioctyl phthalate) as the carrier liquid was described by Yáñez-Flores et al [14] and Rodríguez-Fernández et al [15]. Using the ferrofluid, superparamagnetic properties were achieved.…”

Superparamagnetic particles were widely used in medical applications as well as for magnetic sensors and actuators. Generally, the size of the particles is in the range of 10-20 nm. To use such particles in large-scale applications, a simple processing as well as the use of commercially available particles is required. Therefore superparamagnetic nanoparticles available on the market were incorporated in flexible polymer films and the magnetic properties of the films were investigated. At ambient temperature no significant hysteresis was observed, indicating the superparamagnetic properties. Films containing up to 25% nanoparticles were prepared. The films show a saturation magnetization of 13.8 Am 2 /kg and a coercivity of 7 Oe at ambient temperature.
