摘要/Abstract

摘要： 为防止纳米铝粉在空气中进一步氧化失活，在氮气气氛下，利用硅烷偶联剂对纳米铝粉预处理，后用聚叠氮缩水甘油醚(GAP)对其进行表面包覆改性，得到纳米Al/GAP复合粒子(n-Al/GAP)。采用扫描电镜(SEM)、透射电镜(TEM)、能谱分析仪(EDS)、X射线衍射仪(XRD)、傅里叶变换红外(FTIR)光谱及X射线光电子能谱(XPS)对其形貌和结构进行了表征。用差示扫描量热仪(DSC)对ADN(二硝酰胺铵)、n-Al/ADN和(n-Al/GAP)/ADN的热分解反应特性进行了研究。结果表明:偶联剂在GAP与纳米铝粉之间起到了桥梁的作用，GAP包覆纳米铝粉形成核壳结构复合粒子；n-Al和n-Al/GAP对ADN液化温度几乎没有影响，但使其分解温度均明显提高，且n-Al/GAP影响更为显著。

Abstract: In order to prevent aluminum nanoparticles further oxidation and inactivation in the air，aluminum nanopowders(n-Al)were pretreated with silane coupling agents，then coated with glycidyl azide polymer (GAP)under nitrogen atmosphere. Nano-Al/GAP composite particles(n-Al/GAP)were obtained. The surface morphologies and structures were characterized by scanning electron microscope(SEM)，transmission election microscope(TEM)，energy spectrum instrument(EDS)，X-ray diffraction(XRD)instrument，Fourier transform infrared(FTIR)and X-ray photoelectron spectroscopy (XPS). The thermal decomposition processes of composite systems，such as ADN，n-Al/ADN and(n-Al/GAP)/ADN，were investigated using differential scanning calorimetry(DSC). The results show that the coupling agent plays a role as a bridge between GAP and aluminum nanopowders，and the core-shell composite particles are observed. n-Al and n-Al/GAP have little influence on the liquefaction temperature of ADN，but the decomposition temperature increases significantly，and the effect of n-Al/GAP is more significant.
