“…Liu et al (2011) have obtained monodisperse magnetic PS/Fe 3 O 4 microspheres with a mean size of 1078 nm, which is prepared by the soap-free emulsion polymerization and magnetic colloid swelling polymerization. Naeemikhah et al (2019) have synthesized the magnetic crosslinked PS with hydrophilic nature by the solvent-free surface-initiated atom transfer radical polymerization method, and the organically modified Fe 3 O 4 is used as the polyaddition initiator.…”

A series of colorized and magnetic polystyrene/Fe3O4 (PS/Fe3O4) composite beads with millimeter size are successfully synthesized by introducing hydrophobic Fe3O4via in situ suspension polymerization of styrene for the first time. Effects of the hydrophobic Fe3O4 content, stirring speed, and surfactant dosage on the macromorphology and particle size of PS/Fe3O4 beads are systematically investigated to realize the controllable synthesis. Moreover, three kinds of hydrophobic pigments are also employed to synthesize colorized polystyrene, which demonstrates the versatility, simplicity, and wide applicability of the proposed method. Scanning electron microscopy (SEM) and element mapping (EM) images demonstrated that the hydrophobic Fe3O4 is well dispersed in the polystyrene matrix. Thermogravimetric analysis (TGA) shows that the resultant PS/Fe3O4 beads possess a better thermal stability than neat PS. PS/Fe3O4 beads have a promising application in the fields of colorized extruded PS board, colorized expanded PS foam particle, and board.
