中文摘要: 等离子体中存在大量的电子、正负离子、自由基等高能粒子。活泼气体等离子体中的高能粒子能直接与C60进行加成反应。C60可作为良好的电子受体,最多可以接受6个电子,故等离子体中高能粒子可以诱导C60生成三线态的C60,或捕获电子生成负离子等中间体并与有机小分子/聚合物发生反应。本项目拟采用不用类型的等离子体诱导C60进行反应,根据反应得到的产物结构,重点阐明等离子体诱导C60反应的机理及碳纳米管的反应机理,探索等离子体在C60等碳材料衍生化方面的应用,为功能化材料合成、制备提供一种新技术和新方法

英文摘要: Plasma contains many high-energy particles such as negative electrons, anions, cations and radicals, which can be used to react with C60, giving additonal products, due to the fact that of C60 is a good electron acceptor that can accept up to six electrons. C60 can be induced by plasma to accept electrons, giving 3C60* or C60 aninons, which can further react with other small molecule organic compounds/polymer. In this project, different plasma will be introduced to react with C60 and the additional products will be characterized. The reaction mechanism under plasma (key of this project) will be investigated both experimental and theoretically. Moreover, the application of plasma to synthesize new materials will be explored based on the above results.
