Multi-Step Purification of Single-Wall Carbon Nanotubes
- Detailed Technology Description
- Multi-Step Purification of Single-Wall Carbon Nanotubes A new method to improve the purity and quality of single wall carbon nanotubes (SWNTs)
- *Abstract
-
Advantages
- Results in high purity SWNTs (<1 wt. % metal) with low amorphous carbon residue
- High purity allows for applications more sensitive to quality
- Method is rapid and adaptable to continuous processing
- Process is readily scalable for processing large quantities of SWNTS
Technology
Rice scientists have developed a method for purifying single wall nanotubes which yields high purity product with essentially no damage to the sidewall structure. The carbon yield of the method of this invention (~70%) is significantly higher than that of existing purification methods. Novel techniques allow for optimization of carbon yield and reaction time.
Potential Applications
The unique purity and quality of SWNTS purified according to the subject invention make them suitable for any number of applications with high-performance properties, and especially electronic and magnetic devices.
Patent Status
A utility patent application has been filed with the U.S. Patent and Trademark Office.
