Dry adhesive based on carbon nanotubes gets stronger, with directional gripping ability
Date:10/9/2008

lications may be less glamorous. Because carbon nanotubes conduct heat and electrical current, the dry adhesive arrays could be used to connect electronic devices.

"Thermal management is a real problem today in electronics, and if you could use a nanotube dry adhesive, you could simply apply the devices and allow van der Waals forces to hold them together," Wang noted. "That would eliminate the heat required for soldering."

Another application might be for adhesives that work long-term in space. "In space, there is a vacuum and traditional kinds of adhesives dry out," Dai noted. "But nanotube dry adhesives would not be bothered by the space environment."

In addition those already mentioned, the research team also included Liangti Qu from the University of Dayton, Morley Stone from the Air Force Research Laboratory, and Zhenhai Xia from the University of Akron.

Qu, a research assistant in the laboratory of Liming Dai, grew the nanotube arrays with a low-pressure chemical vapor deposition process on a silicon wafer. During the pyrolytic growth of the vertically-aligned multi-walled nanotubes, the initial segments grew in random directions and formed a top layer of coiled and entangled nanotubes. This layer helped to increase the nanotube area available for contacting a surface.

Qu noted that sample purity was another key factor in ensuring strong adhesion for the carbon nanotube dry adhesive.

For the future, the researchers hope to learn more about the surface interactions so they can further increase the adhesive force. They also want to study the long-term durability of the adhesive, which in a small number of tests became stronger with each attachment.

And they may also determine how much adhesive might be necessary to support a human wearing tights and red mask.

"Because the surfaces may not be uniform, the adhesive force produced by a larger patch may not increase linearly with
