Magnetic polymer microspheres have attracted a great deal of attention due to their magnetic properties and good biocompatibility. In this study, novel magnetic cross-linked poly(divinylbenzene-co-acrylic acid) microspheres were successfully prepared via improved emulsion polymerization. The microstructures of nanocomposites were characterized using scanning electron microscopy, transmission electron microscope, energy-dispersive X-ray spectrometry, X-ray diffraction, and saturation magnetization measurements. It was noteworthy that the nanocomposites displayed good water dispersibility, a rapid absorption rate, a high absorption capacity, and high magnetic separability, results that are promising in terms of these nanocomposites’ future application in biomedical fields.
