Mr Carey made his discovery when hewas testing the properties of a material made of carbon nanotubes and a rubbery polymercalled polydimethylsiloxane.
凯利在测试一种材料的属性时有所发现,该材料的成分包含碳纳米管和一种名为聚二甲基硅氧烷的橡胶聚合物。
He created this composite by growing a forest of nanotubes using hot hydrocarbon gases andan iron catalyst, and then filling the space between the tubes with the polymer.
材料的合成过程是这样:首先,他使高温碳氢混合气体和铁催化剂相互作用产生密集的碳纳米管群,然后再用聚合物充填碳纳米管间的空隙。
The surprise came when he discovered how his new material responded to repeated stress.
当他注意到新材料受到连续作用力而产生反应时,令他惊讶的现象出现了。
He found this did not cause any of the damaging fatigue that would be expected.
据他观察,预期中的材料损毁性疲劳并未产生。
Indeed, his initial inspection suggested the stuff was actually growing stiffer.
实际上,他的初步监测显示材料变得更加坚硬了。
Fascinated by this result, he took his finding to his supervisor, Pulickel Ajayan,
这个结果让凯利喜出望外,他马上找到了自己的导师普里克尔阿贾扬,
