爬上“梯子”摘星星,坐着“电梯”去月亮……这些科幻的场景或将变为可能。《科学美国人》杂志曾提出“在地球与月亮之间搭建一座天梯”的诱人梦想,跨越38万公里的距离而不被自身重量拉断的材料,只有碳纳米管,并且要批量生产,具有宏观长度、理论力学性质,单根长度达到米级甚至公里级才可以。近期,清华大学魏飞教授团队成功制备出世界上最长的、单根长度达半米以上的碳纳米管,创造了新的世界纪录。这一纪录较之前提高了1倍多,这也
Climb the “Ladder” to pick the stars and sit on “Lift” Go to the moon ... These sci-fi scenes or will be possible. Scientific American magazine has put forward the attractive dream of “building a ladder between the earth and the moon,” crossed the 380,000-kilometer distance without being broken by its own weight, with only carbon nanotubes, Production, with macro-length, the theoretical mechanics, a single length of meters or even kilometers before they can. Recently, Professor Wei Fei from Tsinghua University successfully produced the world’s longest single carbon nanotube with a length of more than half a meter and created a new world record. This record more than doubled from the previous one, which is also
