| 摘 要： | 为了提高硝化纤维素(NC)的热分解性能,以硝化石墨烯(NGO)作为含能燃烧催化剂与NC进行复合,制备了NGO/NC复合含能材料。采用傅里叶变换红外光谱(FT-IR)和场发射扫描电子显微镜(SEM)分别研究了NGO/NC复合含能材料的结构和形貌,采用同步热分析仪(TG-DSC)研究了NGO对NC热分解的催化性能。结果表明,当NGO的添加量为1%时,NC的结构不会明显改变,NGO/NC复合含能材料为多孔的三维网络状,且NC的表观分解热由339 J·g~(-1)增加至2132 J·g~(-1),放热峰温度由201℃提高至213℃,质量损失为96%,表明NGO的加入提高了热稳定性,增加了表观放热量。

| Abstract: | In order to enhance the thermal decomposition property of nitrocellulose(NC),an energetic combustion catalyst nitrated graphene oxide(NGO) was introduced to NC and NGO/NC energetic composites were prepared.Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscope(SEM) were used to investigate the structure and morphology of NGO/NC energetic composites,respectively.The thermal decomposition properties of NC in the presence of NGO were characterized through thermogravimentry-differential scanning calorimetry(TG-DSC).With the NGO addition amount of 1％,the structure of NC does not obviously change and NGO/NC energetic composition possesses a porous three-dimensional network structure.The apparent decomposition heat of NC enhances from 339 J · g-1 to 2132 J · g-1 with a mass loss of 96％ and the exothermic peak temperature increases from 201 ℃ to 213 ℃,indicating that the addition of NGO can enhance the apparent decomposition heat and thermostability of NC. |
