【摘要】：基于正交设计理论、采用化学液相沉淀法制备La2O3/CNTs二元纳米复合粒子,用傅立叶变换红外光谱仪(FTIR)、X射线衍射仪(XRD)两种仪器对其进行表征。利用OPT-2000型光谱光度计对不同附加物烟火药配方的发光强度以及光谱图进行测试,采用热分析手段探讨了不同附加物对高氯酸钾的热分解影响。研究结果表明,制备La2O3/CNTs二元纳米复合粒子的最佳条件为碳纳米管与氧化镧质量比1:0.08、转速达到1300r/min、水浴温度为40℃、煅烧温度为700℃。经傅里叶变换红外分析与X射线衍射分析得出氧化镧粒子能够在碳纳米管表面负载,粒径为45.9nm。通过络合滴定分析,可知氧化镧在碳纳米管上的负载量为62%。含纳米复合粒子的La2O3/CNTs-Al-KCl O4配方的发光强度优于单一添加物的纳米La2O3-Al-KCl O4的配方以及CNTs-Al-KCl O4的配方,其发光强度可达到379.933lx,对不同配方烟火药光谱图分析可得到与光强度相吻合及La2O3/CNTs-Al-KCl O4配方的发光强度最大的结论。通过热分析手段最终得出纳米复合粒子La2O3/CNTs的催化效应优于纳米氧化镧与纯化的碳纳米管。
[Abstract]:Based on orthogonal design theory, binary La2O3/CNTs nanoparticles were prepared by chemical liquid precipitation method and characterized by Fourier transform infrared spectroscopy (FTIR) (FTIR) X-ray diffractometer (XRD). The luminescence intensity and spectra of different additives were measured by OPT-2000 spectrometer. The thermal decomposition of potassium perchlorate was investigated by thermal analysis. The results show that the optimum conditions for preparing La2O3/CNTs binary composite particles are: mass ratio of carbon nanotubes to lanthanum oxide 1: 0.08, rotational speed 1300r / min, water bath temperature 40 鈩，
