The amazing properties of carbon nanotubes and their potential has quickly been recognised. One current drawback with nanotubes is that it has only been possible to lay them down at random, which has made exploiting these amazing properties much more difficult.
Nano engineers at Nanyang Technological University in Singapore have come up with a simple solution.
They suggest suspending the nanotubes in water and passing the fluid through narrow channels. The nanotubes would only be able to pass through the channels if they are aligned with the direction of flow.
When the liquid is drained, the aligned nantotubes settle into place creating a material in which the extraordinary properties of carbon nanotubes can be exploited to the full.
