文摘：Carbon Nanotubes (CNTs) are cylindrical structures of pure carbon with walls a single atom thick and, despite being 10,000 times smaller than human hair, CNTs have many unique properties, including: Harder than a diamond; 100 times stronger than steel; 1,000 times the current capacity of copper. When CNTs and their properties were discovered in 1991, and considerations made for how materials would react with increasing number of these miracle tubes inside them, they were hailed as the next material science revolution that would change materials and the products they made forever. The unimaginable would become possible: paper-thin antiballistic vests, super-light airframes, and even space elevators would all become feasible with the incredible properties of CNTs. However, even though CNTs really do have these and many more amazing properties, there were no sensational, CNT-loaded materials released in 1991 - or since. And there is a very good reason for that. The main challenge with CNTs is when they are manufactured, they agglomerate (or clump) into balls of millions and sometimes billions of tubes. And despite there being so many CNTs in these clumps, this agglomeration proves their downfall. Clumped CNTs not only prevent their unique properties from being transferred into a receiving system, but they also end up being detrimental to the receiving system.
