纳米复合材料的特殊性能和用途越来越受到人们的重视.Datta及Roy等曾报道用溶胶-凝胶法制备纳米复合材料,但制备需要经过高温热处理或高温氢气还原.最近,我们将γ射线辐照与溶胶-凝胶法结合起来,在常温常压下成功地制备出非晶SiO_2-Ag纳米复合材料.其制备方法:用分
The special properties and applications of nanocomposites have drawn more and more attention.Datta and Roy et al. Reported that nanocomposites were prepared by sol-gel method but their preparation required high temperature heat treatment or high temperature hydrogen reduction. Recently, Irradiation and sol-gel method combined, at room temperature and pressure successfully prepared amorphous SiO_2-Ag nanocomposites and its preparation method:
