Mirrors take root in pitch-black nanotube forest

Abstract:
REFLECT on this: a gentle push is all it takes to turn the blackest material in the world into a shiny mirror. What's more, combining the two extremes in one substance could open up applications in optical sensors and bendy electronics.

The dark material is a "forest" of vertical carbon nanotubes that absorb more than 99 per cent of incoming light. Kenichi Takahata and colleagues at the University of British Columbia in Vancouver, Canada, discovered they could make the nanotubes reflective by bending a few "trees".
