20150064396 | METHOD FOR SELECTIVELY ANCHORING AND EXPOSING LARGE NUMBERS OF NANOSCALE STRUCTURES - Methods for fastening nanoscale structures within an anchoring structure to form a nanostructure composite and nanostructure composites formed therefrom. A primary fluid layer is formed on an anchoring substrate. Nanostructures are provided on an initial substrate, the nanostructures having a defined height and orientation with respect to the initial substrate. The nanostructures are introduced to a desired depth in the primary fluid layer, such that the orientation of the nanostructures relative to the growth substrate is substantially maintained. The primary fluid layer comprises one or more fluid layers. Ones of multiple fluid layers are selected such that when altered to form an anchoring structure, a portion of the anchoring structure can be removed, permitting exposure of at least a portion of the nanostructures from the anchoring structure in which they are affixed. The growth substrate is removed. Ends or other parts of nanostructures may be exposed from the anchoring structure. | 03-05-2015 |
