瑞士科学家通过高能电子照射使碳纳米管束强度大大提高。这一成果突破了制约碳纳米管基材料实际应用的瓶颈,将对超强纳米管基结构的成型产生重大影响。单壁碳纳米管是目前所知强度最高的材料,但是这一优越的机械特性却还不能在实际生活中发挥作用。原因之一是将它们制成宏观纳米管复合材料(如纳米管纤维束)后,材料强度却很低。因为形成纤维束后,单个碳纳米管之间只有微弱的范德华力作用,在机械 Swiss scientists have greatly enhanced the strength of carbon nanotube bundles by high-energy electron irradiation. This achievement has broken through the bottleneck that restricts the practical application of carbon nanotube-based materials and will have a significant impact on the formation of super-strong nanotube-based structures. Single-walled carbon nanotubes are the most powerful materials known to date, but this superior mechanical properties have not yet been able to function in real life. One of the reasons is that the material strength is low when they are made into macroscopic nanotube composites such as nanotube bundles. Because the formation of fiber bundles, the single carbon nanotubes only van der Waals force between the role of machinery
