If you build your stretchy nanotubes into a honeycomb-like web they can recover better from failures, say Min Wang, Xinming Qiu, & Xiong Zhang from Tsinghua University.
While it looks like a fish-net, the atomic scale changes the way things work:
the forces that determine the nanostructure’s properties are actually quite different from those of a macroscopic honeycomb or fishnet because of the great scale difference. For example, the scientists indicate that the van der Waals interactions & the recombination of bonds at the atomic level would affect the results when the structure is stretched.
The result is that the honeycomb can load-share much better than “straight” nanotubes, leading to it facing the (inevitable) wear-&-tear better.
Interesting new materials should result.
Here is another molecular honeycomb forming, this time naturally.
