Carbon nanotube dry adhesive holds in extreme cold, strengthens in extreme heat

Researchers from Case Western Reserve University, Dayton Air Force Research Laboratory and China have developed a new dry adhesive that bonds in extreme temperatures—a quality that could make the product ideal for space exploration and beyond.
The gecko-inspired adhesive loses no traction in temperatures as cold as liquid nitrogen or as hot as molten silver, and actually gets stickier as heat increases, the researchers report.
The research, which builds on earlier development of a single-sided dry adhesive tape based on vertically aligned carbon nanotubes, is published in the journal Nature Communications (“Carbon nanotube dry adhesives with temperature-enhanced adhesion over a large temperature range”). As far as the researchers know, no other dry adhesive is capable of working at such temperature extremes.
