Abstract

The preparation, synthesis and characterization of micrometer-sized hemispherical magnetic/non-magnetic monodispersed polystyrene/poly(methyl methacrylate) (PS/PMMA) composite particles was discussed. Thermogravimetric and elemental analysis showed that the magnetic content of the magnetic PS microspheres is approximately 10%. The magnetic PS microspheres were then used as template for the preparation of hemispherical magnetic/non-magnetic PS/PMMA composite particles. The completion of the swelling process was verified by the disappearance of the small droplets of the emulsified methyl methacrylate (MMA) from the swollen particles dispersion as observed by light microscopy.
