US Patent:

20030012951, Jan 16, 2003
Filed:

Feb 22, 2002
Appl. No.:

10/079834
Inventors:

Mark Clarke - League City TX, US
Pavel Nikolaev - Houston TX, US
Sivaram Arepalli - Houston TX, US
International Classification:

B05D001/00
B32B005/02
US Classification:

428/398000, 427/008000, 427/372200, 428/299100, 428/293700
Abstract:

Methods of analyzing single-walled carbon nanotube structures dispersed in aqueous solutions with dispersal agents are accomplished by depositing the structures in solution on a suitable substrate and forming an array of isolated structures that are substantially free of contaminating material. Transmission electron microscopy and atomic force microscopy are utilized to characterize the isolated structures formed on the substrate.
