| 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． |
