摘要
在纳米结构的ＳｉＯ２气凝胶的基础上，实验合成了一系列新型的以纳米ＳｉＯ２气凝胶为骨架的多元纳米复合材料．讨论了一系列多组分ＳｉＯ２纳米气凝胶材料的微观纳米结构形式，包括胶粒尺寸、微孔尺寸分布等，同时探讨了在含金属组分的气凝胶骨架上采用气相裂解乙炔的方法制备出以Ｃ－ＳｉＯ２气凝胶为骨架的纳米复合材料与气凝胶骨架中的金属原子的关系，并初步测定了几种ＳｉＯ２纳米复合气凝胶材料的基本物理性能，进一步展望了这些纳米复合材料的可能应用前景．
Synthesis of some nano_composite materials based on SiO2 aerogel-skeleton is reported. The micro_structure of the nano_composite,including particle size,pore size distribution is discussed. The relation of metallic ion in SiO2 aerogel and carbon-silica aerogel nano_composite prepared by acetylene vapor decomposition was investigated. Some behaviors of the nano_composite based on SiO2 aerogel skeleton were determined. The prospect of application of the nano_composite based on SiO2 aerogel-skeleton in future is discussed.
