In this paper, the ultrafine Fe-O compound/ammonium perchlorate (AP) nanocomposites were prepared via in-suit growth method. The structure and morphology of the nanocomposites were characterized by infrared spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion X-ray spectrometer (EDS) and transmission electron microscopy (TEM) test. The results showed that the prepared Fe-O compound nanoparticles were amorphous state and deduced as 2L-ferrihydrite. The size of Fe-O compound/AP nanocomposites could be effectively controlled by changing the recrystallization condition. 2L-ferrihydrite nanoparticles was evenly dispersed in the nanocomposites proved by EDS and TEM analysis. Furthermore, the thermal decomposition of Fe-O compound/AP nanocomposites was analysized by TG-DSC method. The prepared 2L-ferrihydrite nanoparticles of the nanocomposites showed good catalytic effect on AP because of their decreasing the decomposition temperature and increasing the total heat release of AP.

套房内生长法制备超细Fe-O /高氯酸铵纳米复合材料及其表征

本文采用室内生长法制备了超细的Fe-O化合物/高氯酸铵(AP)纳米复合材料。通过红外光谱,X射线衍射(XRD),扫描电子显微镜(SEM),能量色散X射线光谱仪(EDS)和透射电子显微镜(TEM)测试表征了纳米复合材料的结构和形态。结果表明,所制备的Fe-O化合物纳米颗粒为非晶态,并被推导为2L亚铁水合物。通过改变重结晶条件,可以有效地控制Fe-O化合物/ AP纳米复合材料的尺寸。通过EDS和TEM分析证明,2L-水铁矿纳米颗粒均匀分散在纳米复合材料中。此外,通过TG-DSC方法分析了Fe-O化合物/ AP纳米复合材料的热分解。
