离子束辐照通常被认为导致材料产生缺陷,形成无序结构,从而破坏材料的性能。但是,最近利用离子束辐照碳纳米管的实验显示离子束辐照碳纳米管形成无定形的过程不能用传统的离子束辐照材料的机制来解释,离子束辐照可导致碳纳米管形成一些自组装结构,如无定形碳纳米结和碳纳米管连接结等。研究还发现离子束辐照的碳纳米管薄膜在导电性和场发射性能方面都能得到明显的增强。
Ion beam irradiation is generally considered to lead to material defects, the formation of disordered structure, thereby undermining the performance of the material. However, recent experiments using ion beams to irradiate carbon nanotubes have shown that the process of ion beam irradiation to form amorphous carbon nanotubes can not be explained by the mechanism of irradiating the material with a conventional ion beam, and ion beam irradiation can cause the formation of carbon nanotubes Some self-assembled structures, such as amorphous carbon nano-junction and carbon nanotube junction. The study also found that ion beam irradiation of carbon nanotube films in the conductivity and field emission properties can be significantly enhanced.
