氧化锆气凝胶的制备方法研究进展

摘要

ZrO2气凝胶以其独特性质受到人们的广泛关注,对ZrO2气凝胶的结构、性质和制备方法进行了综述,制备方法包括有机锆盐原料法(锆醇盐水解法)和无机盐原料法(滴加环氧丙烷法、无机分散溶胶-凝胶法等).其中,滴加环氧丙烷法是制备高性能ZrO2气凝胶非常有发展潜力的方法之一.%Zirconia aerogels has been paid great attention for its unique properties. This paper summarizes the structure and various preparation methods of zirconia aerogels. The preparation methods include organic salt hydrolyse method (zirconia alkoxide hydrolyse method) and inorganic salt hydrolyse method (addition of propylene oxide method, dispersed inorganic sol-gel method). The addition of propylene oxide method is one of the most potential route for the synthesis of high performance zirconia aerogels.
