Carbon nanotubes are at the center of the nanoelectronics research movement, with scientists making great progress toward getting nanotube-based electronic devices into the hands of consumers. But one area of carbon nanotube research where there has been considerably less success is creating repeating, regular patterns onto individual nanotubes, a task necessary for a key goal of nanoelectronics: patterning transistors directly onto nanotube surfaces.
Now, as reported in a recent edition of Nature Nanotechnology, a research group has successfully used polymers to create well defined patterns onto single-walled carbon nanotubes.
"Very few reports have address periodic patterning on nanotubes, and those studies that have been conducted resulted in patterns that were poorly repeating rather than nicely periodic and uniform," said the study's corresponding researcher, Christopher Li of Drexel University, to PhysOrg.com. "The success of our work appears to be in the polymer material we used."
