Abstract
Multilayered or multitiered structures formed by stacking of vertically aligned carbon nanotube (CNT) arrays and methods of making and using thereof are described herein. Such multilayered or multitiered structures can be used as thermal interface materials (TIMs).
Claims27
A method of forming a multilayered or multitiered structure comprising the steps of:
- (1) providing at least two or more carbon nanotube arrays or sheets;
- and
- (2) stacking the at least two or more carbon nanotube arrays or sheets;
- wherein the stacking results in at least partial interdigitation of carbon nanotubes of the at least two or more arrays or sheets thereby forming two or more layers or tiers.

A multilayered or multitiered structure comprising:
- at least a first layer or tier comprising a carbon nanotube array or sheet, and
- at least a second layer or tier comprising a carbon nanotube array,
- wherein the carbon nanotubes of the array or sheet of the first layer or tier at least partially interdigitate the carbon nanotubes of the array or sheet of the second layer or tier to form the multilayered or multitiered structure.

A device comprising a multilayered or multitiered structure comprising:
- at least a first layer or tier comprising a carbon nanotube array or sheet, and
- at least a second layer or tier comprising a carbon nanotube array,
- wherein the carbon nanotubes of the array or sheet of the first layer or tier at least partially interdigitate the carbon nanotubes of the array or sheet of the second layer or tier to form the multilayered or multitiered structure, and wherein multilayered or multitiered structure comprises a coating material present in at least some of the interstitial space between the carbon nanotubes, on the surfaces of the carbon nanotubes, or both, of the at least first and second layers or tiers of the multilayered or multitiered structure.
