Study on the Reaction of C60 under Shock Wave
-
摘要: 采用爆轰波驱动飞片,对C60样品进行冲击实验,实验产生的烟灰经甲苯萃取后,采用高效液相色谱进行成份分析。结果表明:冲击波的高温高压作用使C60样品大部分分解,少部分形成高碳富勒烯、富勒烯包合物和其它碳簇产物。研究了不同冲击波作用下,C60样品的压强、温度的变化及对C60反应的影响,并对C60的分解与聚合的作用机理进行了探讨。Abstract: Using detonation-driven flyer, the samples of C60 were shock loaded. For toluene extraction, the soot was examined by high performance liquid chromatography (HPLC). The results showed that most of C60 was decomposed, a small part was changed into polymer, high fullerene, endohedral and other carbon cluster under shock wave high temperature high pressure. Under the shock waves of differentintensity, the influence of the temperature and pressure on the decomposition and polymerization of C60 were studied. The destruction mechanism of C60 and the formation of the polymer of C60 were also discussed.
