本文综述了无机纳米粒子与聚合物基质组成的纳米复合材料在光学和磁性方面的最新研究进展。当颗粒尺寸减小到非常小的尺寸时，光学或磁性可以改变，这通常是纳米复合材料领域的主要兴趣。将无机纳米粒子应用到聚合物基质中，可以提供高性能的新型材料，这些材料在许多工业领域都有应用。在这方面，经常考虑的特征是光学属性，例如光吸收(UV和颜色)和光散射的程度，或者在金属颗粒的情况下，光致发光、二色性等，以及磁性属性，例如超顺磁性、电磁波吸收和电磁干扰屏蔽。简要介绍了聚合物-无机纳米复合材料的定义、发展历史，并对聚合物-无机纳米复合材料的合成技术进行了综合评述。展望了纳米复合材料在光学和磁学领域的发展前景。预计新型功能性无机纳米填料的使用将导致新型聚合物-无机纳米复合材料具有独特的材料性能组合。通过仔细选择合成技术和了解/利用此类材料中聚合物纳米复合材料的独特物理性质，可以设计和制备新型功能聚合物-无机纳米复合材料，用于新的有趣的应用，如光电子和磁光应用。
This article provides an up-to-date review on nanocomposites composed of inorganic nanoparticles and the polymer matrix for optical and magnetic applications. Optical or magnetic characteristics can change upon the decrease of particle sizes to very small dimensions, which are, in general, of major interest in the area of nanocomposite materials. The use of inorganic nanoparticles into the polymer matrix can provide high-performance novel materials that find applications in many industrial fields. With this respect, frequently considered features are optical properties such as light absorption (UV and color), and the extent of light scattering or, in the case of metal particles, photoluminescence, dichroism, and so on, and magnetic properties such as superparamagnetism, electromagnetic wave absorption, and electromagnetic interference shielding. A general introduction, definition, and historical development of polymer–inorganic nanocomposites as well as a comprehensive review of synthetic techniques for polymer–inorganic nanocomposites will be given. Future possibilities for the development of nanocomposites for optical and magnetic applications are also introduced. It is expected that the use of new functional inorganic nano-fillers will lead to new polymer–inorganic nanocomposites with unique combinations of material properties. By careful selection of synthetic techniques and understanding/exploiting the unique physics of the polymeric nanocomposites in such materials, novel functional polymer–inorganic nanocomposites can be designed and fabricated for new interesting applications such as optoelectronic and magneto-optic applications.
