中文摘要：

磁性纳米颗粒由于具有不同于大块样品的物理和化学性质,因而在日常生活中具有广泛的应用并且日趋复杂,因此控制磁性纳米材料的稳定性及表面的功能化就变得尤为重要。聚合物作为覆盖层可以很好地控制磁性纳米颗粒的成核、生长和团聚,此外,两者复合后还可改善聚合物的性质。评述了近些年来聚合物磁性纳米复合物的研究进展,并提出了纳米复合物需要解决的问题。

英文摘要：

Due to their physical and chemical properties different from their bulk state, magnetic nanoparticles are applied in many fields in daily life and its applications become more sophisticated, so precise control over the stability and surface functionality are critical. Polymer used as coating provides a matrix for binding of the particles and can control the nucleation, growth and agglomerations. In addition, the integration of magnetic particles with polymer can iraprove the performance of the polymers. In this paper, the is reviewed and the main problems that should be solved development of magnetic nanocomposites with polymer matrix in the future are also discussed.
