主要采用硝酸铜、柠檬酸、油酸和RDX成功制作了含有铜离子的溶胶凝胶前驱体炸药,并在密闭容器中氩气保护下炸药爆轰合成了球形、颗粒尺寸均匀、核壳结构的石墨包覆铜纳米颗粒(Cu-Gs)。采用XRD、TEM、Raman等表征了爆轰产物的结构组成、形貌特征及包覆层构成。通过优化设计调整前驱体炸药的元素摩尔组成、密度及氧平衡,从而来寻求控制合成Cu-Gs的途径。最后简要讨论了Cu-Gs的生长机理。 Mainly using copper nitrate, citric acid, oleic acid and RDX successfully produced a sol precursor precursor containing copper ions explosive, and detonated in a sealed container under argon explosive synthesized spherical, uniform particle size, core-shell structure Graphite-coated copper nanoparticles (Cu-Gs). The structure, morphology and coating composition of detonation products were characterized by XRD, TEM and Raman. By optimizing the elemental molar composition, density and oxygen balance of the precursor explosives, the way to control the synthesis of Cu-Gs was sought. Finally, the mechanism of Cu-Gs growth is briefly discussed.
