溶胶一凝胶法不仅具有可在低温、溶液中进行制备，达到分子级的分散水平的特点，而且为有机／无机复合材料，尤其是纳米复合材料的制备开辟了新途径。本文在概述了溶胶─凝胶法基本原理的基础上，着重评述了该方法在制备高分子／无机复合材料方面的特殊应用。
Sol-gel method not only has the characteristics of low temperature, the preparation of the solution to achieve the molecular level of the dispersion level, but also for the organic / inorganic composite materials, especially the preparation of nanocomposites opened up a new way. Based on the basic principles of sol-gel method, this paper mainly reviews the special application of this method in the preparation of polymer / inorganic composites.
