A couple of snapshots from yesterday’s NanoTech adventure.
The thing is… you really can’t see much. That’s true in person, too. This stuff is SO BLACK, elemental carbon black, absorbs-all-light black, that what you end up seeing looks like a hole in the photo – like someone used a “select” tool and just deleted that part.
Seeing that in person is quite strange.
Here, you can see the drafting of the film that eventually gets twisted to make the yarn. In person, it looks like smoke.
They call it a “forest” because the carbon nanotubes are oriented up and down, like trees:
They used a very fine polyester, tied into a structural warp that looks like cotton. This is about the size of my little fingernail.
