碳是人类接触最早,也是利用最早的元素之一。我们每天吃的蔬菜、米饭,使用的纸张、塑料,以及维持人类社会发展的能源,如煤炭、石油等,都是碳的化合物。甚至于构成人体的最小单元——细胞,也是以碳元素为骨架演化而来的。可以说,没有碳,就没有生命。今天,碳家族的新成员——碳纳米管,正吸引了越来越多的科学家的关注。碳纳米管是由碳原子像链条一样连结而成的管状物质,它的管子很细,5万根碳纳米管并排起来才有一根头发丝那么粗。小小的碳纳米管到底有什么魅力让科学家们如此着迷呢?现在,就让我们来一一揭晓吧!
Carbon is the earliest human contact, but also the use of one of the earliest elements. The vegetables we eat every day, rice, paper used, plastics, and energy that sustains human social development, such as coal and oil, are all carbon compounds. Even the smallest cells that make up the human body, the cells, are also evolved from carbon skeletons. It can be said that without carbon, there is no life. Today, a new member of the carbon family, carbon nanotubes, is attracting more and more scientists’ attention. Carbon nanotubes are tubular substances made up of carbon atoms linked like a chain. The tubes are very thin, and 50,000 carbon nanotubes have their hair strands side by side. What are the charm of tiny carbon nanotubes scientists so fascinated? Now, let us come to announce it one by one!
