摘要
介绍一个开放式研究性实验-复合气凝胶(CAG)的制备新方法。该实验以高分子化学反应为基础,通过有机硅水解、缩合聚合、自由基引发聚合等制备复合气凝胶的方法,制备具有多孔结构、孔径分布均匀的CAG凝胶,并通过IR、SEM、N2吸-脱附等进行表征与测试。
Introduced an open research experiment-preparation and characterization of composite aerogels. The experiment based on the theory of polymer modified. The composite aerogels were prepared by hydrolysis, condensation and monomer free radical copolymerization of ethyl orthosilicate, and the composite aerogels with different pore sizes were prepared and characterized through IR, SEM, N2 absorption and desorption.
