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、Fe3O4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 hydrogels have a greater improvement in mechanical properties, optical properties, thermal properties,etc. The preparation of nanocomposite hydrogels with nano-TiO2,nano-SiO2,and nano-Fe3O4 inorganic materials as fillers or crosslinking agent are introduced, and the applications in environmental protection, medicine and other fields are analyzed.
