Ultrathin, ultralight 'nanocardboard'

-
Engineers have demonstrated a new material they call 'nanocardboard,' an ultrathin equivalent of corrugated paper cardboard. A square centimeter of nanocardboard weighs less than a thousandth of a gram and can spring back into shape after being bent in half. Nanocardboard's stiffness-to-weight ratio makes it ideal for aerospace and microrobotic applications, where every gram counts.
