1991年,一个叫饭岛澄男的日本科学家在分析煤烟样本时发现了一种针状的管形碳单质,它的形状如同一个卷起的管子,平均直径只有1～2纳米,大小等同于一个DNA分子。出乎意料地,这种微小的东西很快成了材料科学家眼中的超级明星,他们发现,在诸多材料中,这种物质竟鹤立鸡群般地优秀:轻便,坚硬,散热和导电性能无与伦比。这样的材料在人类的未来生活中会扮演怎样的角色呢?人们不禁自问,并对它寄予无限的希望,他们把这种管状的碳单质称为碳纳米管。
In 1991, a Japanese scientist named Iijima Shimane discovered an acicular tubular carbon element when it analyzed soot samples. It was shaped like a rolled tube with an average diameter of only 1 to 2 nanometers in size equal to A DNA molecule Unexpectedly, this tiny thing quickly became a superstar in the eyes of material scientists who found that in many materials this substance was outstanding: light, hard, unmatched in thermal and electrical conductivity. What kind of material does such a material play in the future of mankind? One can not help but ask ourselves, with infinite hope, of what they call carbon nanotubes.
