酚类衍生物制备纳米材料气凝胶工艺过程研究

Preparation of Nanoporous Aerogels from Phenols Compound

气凝胶是一种新型纳米多孔非晶态材料 ,结构可控。本文以间苯二酚、间甲酚、混合甲酚为原料 ,与甲醛在碱性条件下经溶胶—凝胶过程、超临界干燥得到气凝胶。考察了工艺条件对气凝胶性能的影响 。

Aerogols are a novel nanoporous, noncrystalline material, whose structure can be controlled at nanometer scale. In this paper aerogels were obtained through solgel process of resorcinol, mcresol and cresol mixture and substantially supercritical fluid drying. The effect of techology conditions on the properties was investigated, while the difference of properties of aerogels obtained from three panels also compared.
