摘要
以碳酸钠为催化剂, 乙醇为溶剂, 间苯三酚-乙醛为反应前躯体, 经溶胶-凝胶、交联老化、二氧化碳超临界干燥制备出间苯三酚-乙醛(PA)有机气凝胶。扫描电镜观察和N2吸附测试结果表明:气凝胶具有较高的比表面积, 是一种连续nm级3维网络结构的多孔材料, 其比表面积为1 210 m2/g, 平均孔径为11 nm, 与传统有机气凝胶相比, 提高了比表面积, 一定程度上实现有机气凝胶的扩孔。
Abstract
Organic aerogels were synthesized by sol-gel polycondensation of phlorogluctinol(P)with acetaldehyde(A) in a slightly alcohol solution,Na2CO3 as the base catalyst,followed by crosslink,solvent exchanging,and drying with supercritical carbon dioxide.Organic aerogels were characterized by SEM and nitrogen adsorption.The aerogel has a continuous nano-network and porous structure. Compared with traditional organic aerogels,it has increased specific surface area(1 210 m2/g)and average pore diameter (11 nm),which is expected to meet the requirement of ICF targets.
