An adhesive that holds tight in cold, gets stronger in heat

• newatlas.com by Eric Mack

The gecko-inspired material maintains its hold in extreme cold and actually gets stickier in extreme heat.

Building on previous research, a team of engineers from Case Western Reserve University and Dayton Air Force Research Laboratory created a double-sided tape made of carbon nanotubes that they claim would lose no traction whether applied to cold liquid nitrogen or hot molten silver.

The nanotubes that make up the adhesive are vertically aligned and bundled into nodes similar to the microscopic hairs on a gecko's foot pads that allow it to walk up walls. A number of other adhesives and grippers have been derived from the same inspiration, but this new invention has some notable qualities.
