用溶胶 凝胶法制备出了高RC比 (间苯二酚与催化剂的摩尔比 )的RF有机气凝胶 ,通过溶剂替换 ,成功地实现了常压条件下的干燥工艺。经高温碳化处理 ,将RF有机气凝胶转化为碳气凝胶 ,改变RC比和聚合单体的质量百分数 ,可控制气凝胶的粒径及孔径、密度及比表面积。用扫描电镜 (SEM )、BET等方法对其颗粒大小、密度、比表面积及孔径分布等微结构进行了分析测试。制备出的碳气凝胶性能满足惯性约束聚变靶材要求 RF organic airgel with high RC ratio (molar ratio of resorcinol to catalyst) was prepared by sol-gel method. The solvent drying process was successfully carried out under normal pressure. After the high temperature carbonization process, the RF organic airgel is converted into a carbon airgel, and the mass ratio of the RC ratio and the monomer can be changed to control the particle size, pore diameter, density and specific surface area of ​​the airgel. The microstructure, such as particle size, density, specific surface area and pore size distribution were analyzed by SEM and BET. The performance of the prepared carbon airgel meets the requirement of inertial confinement fusion target
