Abstract
Official abstract text for this publication.
A method of forming a structure having selectively placed carbon nanotubes, a method of making charged carbon nanotubes, a bi-functional precursor, and a structure having a high density carbon nanotube layer with minimal bundling. Carbon nanotubes are selectively placed on a substrate having two regions. The first region has an isoelectric point exceeding the second region's isoelectric point. The substrate is immersed in a solution of a bi-functional precursor having anchoring and charged ends. The anchoring end bonds to the first region to form a self-assembled monolayer having a charged end. The substrate with charged monolayer is immersed in a solution of carbon nanotubes having an opposite charge to form a carbon nanotube layer on the self-assembled monolayer. The charged carbon nanotubes are made by functionalization or coating with an ionic surfactant.
First claim
Opening claim text (preview).
What is claimed is: 1 . A structure having a carbon nanotube (CNT) layer, the structure comprising: a substrate having a first region and a second region; a self-assembled monolayer on the first region; and a CNT layer on the self-assembled monolayer; wherein the CNT layer has a density exceeding 1 CNT per square micron. 2 . The structure of claim 1 , wherein the CNT layer has a density of bundled CNTs of less than 1 CNT bundle per square micron. 3 . The structure of claim 1 , wherein the self-assembled monolayer comprises a precursor molecule having a first functional group to anchor the monolayer to the first region of the substrate and a second functional group having a first ionic charge moiety on a surface of the self-assembled monolayer. 4 . The structure of claim 4 , wherein the CNT layer comprises a second ionic charge moiety, and the first ionic charge moiety and the second ionic charge moiety are oppositely charged.
