    Abstract: A nanocomposite dry adhesive. The nanocomposite dry adhesive includes a substrate; and an array of vertically aligned single-walled carbon nanotubes or vertically aligned multi-walled carbon nanotubes on the substrate, wherein the nanocomposite dry adhesive utilizes the array of single-walled carbon nanotubes or multi-walled carbon nanotubes as synthesized, the as synthesized single-walled carbon nanotubes being substantially free of randomly entangled nanotube segments on top of the vertically aligned single-walled carbon nanotubes, the as synthesized multi-walled carbon nanotubes having randomly entangled nanotube segments on top of the vertically aligned multi-walled carbon nanotubes; wherein the dry adhesive has a normal adhesion strength of at least about 5 N·cm−2, and a shear adhesion strength of at least about 13 N·cm−2. Methods of making a nanocomposite dry adhesive are also described.

    Abstract: The invention is directed to carbon nanostructure composite systems which may be useful for various applications, including as dry adhesives, electronics and display technologies, or in a wide variety of other areas where organized nanostructures may be formed and integrated into a flexible substrate. The present invention provides systems and methods wherein organized nanotube structures or other nanostructures are embedded within polymers or other flexible materials to provide a flexible skin-like material, with the properties and characteristics of the nanotubes or other nanostructures exploited for use in various applications. In one aspect, the invention is directed to a carbon nanotube/polymer composite material having a plurality of carbon nanotubes formed into a predetermined architecture, with each of the plurality of nanotubes having a desired width and length. The architecture of the plurality of nanotubes defines at least one orientation for a plurality of nanotubes, and also defines the approximate spacing between nanotubes and/or groups of nanotubes. The carbon nanotube architecture is at least partially embedded with a polymer matrix in a manner that the architecture is stabilized in the predetermined architecture. The polymer matrix may also be formed to have a desired predetermined thickness.
