摘要 用溶胶-凝胶法结合超临界干燥法,制备了Fe2O3/Al复合含能材料。用SEM、XRD、BET等方法对Fe2O3/Al复合含能材料的结构进行了表征。结果表明,超临界法制备的Fe2O3/Al复合含能材料呈明显的纤维网络状结构;其中Al的平均粒径为40nm;比表面积为147.9m2/g,相比空白Fe2O3气凝胶明显下降,平均孔径为8nm,孔径分布比较均匀。 Fe2O3/Al composite energetic material was prepared by sol-gel method and supercritical fluid drying.Its structure was investigated by means of SEM,XRD and BET.The experimental results showed the structure of Fe2O3/Al composite energetic material was significant fiber network.The average particle size of Al in Fe2O3/Al composite energetic material was 40nm.The specific surface area of Fe2O3/Al composite energetic material was 147.9m2/g,and much smaller than blank Fe2O3 aerogel.Its average pore size was 8nm and the distribution of pore size was more uniform.
