中文摘要：
采用溶液法原位制备了氧化亚铜/多壁碳纳米管（Cu2O/MWNTs）超细复合球.通过扫描隧道显微镜（SEM）、透射电子显微镜（TEM）、X射线衍射仪（XRD）、紫外-可见分光光度计（UV-vis）和差热分析（DSC）等手段对产品进行了形貌分析和性能检测.结果表明：碳纳米管均匀嵌镶在Cu2O球中;相比于同粒径纯Cu2O球,复合球的特征吸收峰发生蓝移,复合球使高氯酸铵（AP）的高温分解温度进一步降低了11.5℃.另外,对复合球的形貌影响因素及生长机理进行了探讨,发现明胶是复合物成球的关键,而聚乙二醇影响复合球粒径的均匀性.
英文摘要：
Cuprous oxide/carbon nanotubes （Cu2O/MWNTs） composite superfine spheres were fabricated in situ by solution method. The products were characterized via scanning electron microscope （SEM）, transmission electron microscope （TEM）, X-ray diffraction pattern （XRD）, UV-vis absorption spectrum and differential scanning calorimetry （DSC）. The results show that the MWNTs are embedded in cuprous oxide spheres homogeneously. Compared with pure Cu2O particle, the absorption peak of composite spheres has a tendency of blue shift, and the temperature of high temperature decomposition of ammonium perchlorate （AP） is further decreased by 11.5℃ when composite spheres act as the catalyst. In addition, the main influence on morphology and the formation mechanism of composite spheres are investigated. Results suggest that the gelatin play a key role in forming spheres and polyethylene glycol have great impact on the uniformity of spheres size.
