| 摘 要： | 以间苯三酚(P)和甲醛(F)为原料，经溶胶-凝胶、溶剂交换、超临界干燥和碳化等过程制备出了间苯三酚-甲醛气凝胶(PF)及其碳气凝胶(CPF)。测试结果表明气凝胶具有比较高的比表面积、是一种连续nm级3维网络结构的多孔材料；碳化后密度和平均孔径增大，比表面积基本无变化，且仍然维持气凝胶的网络结构。催化剂摩尔比决定气凝胶的微观结构，反应物质量分数控制着气凝胶密度。通过优化制备条件，可以制备出能满足惯性约束聚变(ICF)靶需要的不同结构和不同密度的气凝胶。

| Abstract: | Phloroglucinol-formaldehyde(PF) aerogels and carbonized PF(CPF) aerogels were prepared from Phloroglucinol(P) and Formaldehyde(F) by sol-gel,solvent exchanging,supercritical drying and carbonization processes.The aerogel has a large specific surface area,continuous nano-network and porous structure.The density and mean porosity radius will enlarge after being carbonizied,while the specific surface area will be influenced little.The micro-structure and density of aerogel are controlled by concentration of total reactants and catalyzer,respectively.Aerogels with different micro-structure and different density fit for ICF targets can be prepared by optimizing synthesis conditions. |
