Carbon nanotube measurements: latest in NIST 'how-to' series
Date:4/15/2008

The National Institute of Standards and Technology (NIST), in collaboration with the National Aeronautics and Space Administration (NASA), has published detailed guidelines* for making essential measurements on samples of single-walled carbon nanotubes (SWCNTs). The new guide constitutes the current best practices for characterizing one of the most promising and heavily studied of the new generation of nanoscale materials.

The nanotubes are essentially cylinders of carbon atoms with a wall only one atom thick and a diameter of a couple of nanometersbut lengths up to several million times their diameter. (Think of a soup can about 100 kilometers tall.) Because of their unique electronic, thermal, optical and mechanical properties they are being studied for a wideand expandingrange of applications, including ultrastrong fibers for nanocomposite materials, circuit elements in molecular electronics, hydrogen storage components for fuel cells and light sources for compact, efficient flat-panel displays. One basic problem is assuring the quality and purity of SWCNT materials. All known techniques for producing these tiny tubes also produce large quantities of nanojunk: simple graphite and carbon soot often encapsulating small metal particles used to catalyze the nanotube synthesis process. (See, for example, NIST Laser-Based Method Cleans Up Grubby Nanotubes, Tech Beat Dec. 1, 2006.)

Accurate, reliable and preferably rapid measurement techniques are needed to optimize production processes to create more product and less impurities. These will help to control cleaning and purifying processes and ultimately to improve the confidence of buyers and sellers of SWCNT materials. Beginning in 2003, NIST and NASA researchers started addressing the problem by sponsoring a series of workshops devoted to nanotube measurements. The NIST Recommended Practice Guide on Measurement Issues in Single Wall Carbon Nanotubes grew out of second workshop in 2005, and
