据《韩国时报》2005年10月20日报导,韩国浦项科技大学金光洙教授负责的一个小组研制出直径只有0.4纳米的亚纳米碳管。该小组研制出的这种极细纳米管达到了1毫米的长度,比以前的1微米的长度长了很多。据说也是全球第一个亚纳米碳管。报导说,之前最细的碳纳米管的厚度也要超过1纳米,由于该小组采用新的方法超越了这一障碍。碳纳米管是上世纪90年代早期发现的柱状碳分子。它们由于独特的物理和化学特性而被称为理想材料。这些特性使它们 According to “South Korea Times” reported on October 20, 2005, a team led by Prof. Kim Soo-Soo of Pohang University of Science and Technology of Korea developed sub-carbon nanotubes with a diameter of only 0.4 nm. The group developed ultrathin nanotubes that reached a length of 1 millimeter, a lot longer than the previous one micrometer. It is also said to be the world’s first sub-carbon nanotube. The report said that the thinnest carbon nanotubes were more than 1 nanometer thick before, since the group adopted a new approach to transcend the barrier. Carbon nanotubes were the columnar carbon molecules found in the early 1990s. They are called ideal materials due to their unique physical and chemical properties. These characteristics make them
