| 摘 要： | 采用超临界干燥方式和冷冻干燥方式制得RDX/RF气凝胶和干凝胶.利用扫描电镜(SEM),BET比表面积分析,X射线粉末衍射(XRD),差示扫描量热法(DSC)对其结构进行了表征.结果表明: 超临界干燥方式得到的RDX/RF气凝胶具有典型纳米孔洞结构和高比表面积特性.冷冻干燥导致干凝胶骨架结构坍塌,比表面积显著降低.RDX/RF气凝胶中RDX的平均晶粒度在34～38 nm之间,干凝胶中RDX的平均晶粒度在50～100 nm之间.RDX/RF气凝胶和干凝胶的热分解峰分别提前了14～25 ℃和2～7 ℃.

| Abstract: | Hexahydro-1,3,5-trinitro-1,3,5-triazine/resorcinol-formaldehyde (RDX/RF) aerogel and xerogel were prepared by supercritical fluid drying method and freezing drying method. The structure of RDX/RF composites were characterized by scanning electron microscopy (SEM),BET method,X-ray power diffraction (XRD) and differential scanning calorimetry (DSC). The results show that supercritical fluid drying method can get RDX/RF aerogel of typical nano-pore structures and high surface areas. Freezing drying destroys th... |
