Abstract
Ammonium perchlorate (AP), as an oxidant and a main component in solid propulsion, has been of wide concern by researchers in recent years. However, problems, such as higher high-temperature decomposition peaks and nonconcentration of exothermic heat release, hinder its application. The addition of combustion catalysts can resolve these problems, but the small size of metals is prone to agglomeration and affects the performance of AP. Graphene oxide, which has a large specific surface area as a carrier, hydroxyethyl cellulose as an intercalating agent, cobalt nitrate as the three-dimensional porous carbon aerogel were prepared as catalyst for AP. The high-temperature decomposition peak of AP was greatly reduced by 116.5 K, which resulted in a great energy release.
高氯酸铵(AP)作为一种氧化剂和固体推进剂的主要成分,近年来一直受到研究人员的广泛关注。然而,高温分解峰较高、放热不集中等问题阻碍了其应用。添加燃烧催化剂可以解决这些问题,但金属体积小,容易团聚,影响 AP 的性能。以比表面积大的氧化石墨烯为载体,羟乙基纤维素为插层剂,硝酸钴为三维多孔碳气凝胶,制备了 AP 催化剂。AP 的高温分解峰在 116.5 K 时大大降低,从而释放出大量能量。
期刊介绍:
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
