摘要：
Afacile and efficient routewas reported to prepare a kind of yolk-shell magnetic hybrid microspheres by suspension polymerization and calcinations method. The morphology, structure, and composition of the magnetic microspheres were characterized by FTIR, XRD, TEM, SEM, and TGA analysis. The vibrating-samplemagnetometry (VSM) results clearly showed that themagnetic particles were superparamagnetic with saturation magnetization of 32.82 emu/g which makes the microcomposites easily controlled by an external magnetic field. The results revealed that themagnetic hybrid microspheres might have important applications inmagnetic bioseparation and drug delivery.
