Title:
SPATIAL LOCALIZATION OF DISPERSED SINGLE WALLED CARBON NANOTUBES INTO USEFUL STRUCTURES
Document Type and Number:
WIPO Patent Application WO2003053846
Kind Code:
A3
Abstract:
Methods of aligning single walled carbon nanotube structures into selected orientations for a variety of different applications are achieved by initially dispersing the nanotube structures in aqueous solutions utilizing a suitable dispersal agent. The dispersal agent coats each individual nanotube strzcture in solution. The dispersal agent may be substituted with a suitable functional group that reacts with a corresponding binding site. Dispersed nanotube structures coated with substituted dispersal agents are exposed to a selected array of binding sites such that the nanotubes align with trhe binding sites due to the binding of the substituted functional groups with such binding sites. Alternatively, crystalline nanotube material is formed upon deposition of dispersed nanotube structures within solutions into channels disposed on the surface of the substrate. Combining dispersal agent chemical modification techniques with deposition of the nanotubes into substrate channels is also utilized to produce useful structures.
