中文摘要：

纳米材料具有直径小、比表面积大以及易于实现表面功能化的优点,受到广泛的关注.与普通水凝胶相比,将无机纳米材料分散在水凝胶中制备的有机/无机纳米复合水凝胶的力学性能、光学性能、热力学性能都有较大提高.主要综述了TiO2、SiO2、FeO4等无机物作为填充剂或交联剂制备纳米复合水凝胶的方法,如共混法、原位法等,并分析了其在环保、医药等领域的应用.

英文摘要：

Nano-materials with the advantages of small diameter, large specific surface area and easily realized surface functionalization are widely concerned. Organic/inorganic nanocomposite hydrogels were prepared with the nano-sized inorganic particles dispersed in an aqueous gel. Compared with ordinary hydrogel, the nanocomposite hy- drogels have a greater improvement in mechanical properties, optical properties, thermal properties, etc. The prepara- tion of nanocomposite hydrogels with nano-TiOz, nano-SiOz, and nano-Fe3 04 inorganic materials as fillers or crosslin- king agent are introduced, and the applications in environmental protection, medicine and other fields are analyzed.
