以富勒烯乙二胺硝酸盐和二硝酰胺铵(ADN)为原料,通过离子交换反应制备了富勒烯乙二胺二硝酰胺盐,采用紫外-可见光谱(UV-Vis)、傅里叶变换红外光谱(FT-IR)、元素分析和X射线光电子能谱(XPS)等对其结构进行了表征.结果表明,富勒烯乙二胺二硝酰胺盐的分子式为H12C60(HNCH2CH2NH2·HN(NO2)2)12.用差热分析(DTA)、差示扫描量热法(DSC)和热重-微分热重分析(TG-DTG)研究其热分解特性.DSC曲线表明富勒烯乙二胺二硝酰胺盐于150℃开始分解,热分解峰温为203℃,分解焓为1037.7 J·g^-1.TG曲线表明,100~800℃范围内,总失重率49.68%,主要是N(NO2)2-分解和部分支链分解.
Fullerene ethylenediamine dinitramide was synthesized via ion exchange reaction of fullerene ethylenediamine nitrate and ammonium dinitramide (ADN). The structure offullerene ethylenediaminedinitramide was characterized by UV-Vis, FT-IR, elemental analysis and XPS. Its thermal decomposition characteristics were investigated by thermogravimetric-differential thermo- gravimetry (TG-DTG), differential scanning calorimetry (DSC) and differential thermal analysis (DTA). Results show that the molecular formula of fullerene ethylenediamine dinitramide is H12C60(HNCH2CH2NH2 · HN(NO2)2)12. DSC curve shows that fullerene ethylenediamine dinitramide starts to decompose at 150 ℃ with thermal decomposition peak temperature 203 ℃ and decomposition enthalpy 1037.7 J · g^-1. TG study indicats the total mass loss in the temperature range 100-800 ℃ is 49.68% with intense decomposing of N( NO2)-2 and part of the branched chain decomposing.
