摘要/Abstract

摘要： 采用溶胶-凝胶法制备了以硝化棉（NC）为凝胶骨架的NC/黑索今（RDX）纳米复合含能材料，并采用红外光谱（FTIR）、X射线衍射（XRD）、扫描电镜（SEM）以及热失重/差示扫描量热（TG/DSC）等测试手段对材料进行了表征。研究结果表明：RDX与NC凝胶骨架成功复合；由Scherrer公式计算复合材料中RDX的平均粒径最低可达50.16 nm，且随着RDX含量增大，其粒径随之增大，但仍在100 nm以下；复合材料中RDX的最大分解温度及差示扫描量热（DSC）放热峰温均低于原料RDX。

Abstract: NC/RDX nano-composite energetic material with nitro-cellulose(NC) as gel matrix is prepared using sol-gel method, and the material is characterized by FTIR, XRD, SEM and TG/DSC methods. The results show that RDX is successfully composited with NC. The minimum RDX average crystallite size calculated by Scherrer equation is 50.16 nm, and although the crystallite size increases with the increase in RDX content, the maximum crystallite size is less than 100 nm. Both the temperature of maximum decomposition rate and DSC exothermic peak temperature of RDX in composite material are lower than that of RDX raw material.

Key words: ordnance science and technology, NC, RDX, sol-gel method, supercritical fluid drying, nano-composite energetic material
