国外80年代诞生的一种称为“纳米”的新型材料,是前景非常广阔的跨世纪高新技术材料,它将给世界带来新的产业革命。 据中国科学院固体物理研究所所长、纳米科学专家张立德称,物质达到纳米级后,具有常规粗晶粒材料所不具备的奇异特性和反常特性,如铜到纳米级就不导电,而绝缘的二氧化硅及晶体等,到20nm时,却开始导电。纳米技术将给人类带来数十万种性能优异的新型材料。 A new type of material called “nano” born abroad in the 1980s is a very promising cross-century high-tech material that will bring a new industrial revolution to the world. According to Zhang Lide, director of the Institute of Solid State Physics of the Chinese Academy of Sciences and nanoscience expert, after the material reaches the nanoscale, it has the singularity and anomalous properties that the conventional coarse-grained materials do not possess, Silicon dioxide and crystals, etc., to 20nm, but began to conduct electricity. Nanotechnology will bring to humans hundreds of thousands of new materials of outstanding performance.
