摘要：

Superparamagnetic iron oxide particles synthesized in water-in-oil microemulsions have been incorporated into a polymer matrix. The microstructured micellar environment provides a template for polymer synthesis, leading to the formation of interconnected polymer particles with spherical morphologies. The resulting iron oxide-polymer composites reveal superparamagnetic properties and low temperature remanence and susceptibility characteristic of a superparamagnet. The results of temperature and field dependent magnetic characterizations of these composites are described. Ultramicrotomed TEM micrographs show that the iron oxide particles (size < 100 Angstrom) are uniformly distributed in the polymer microspheres.
