Multi-walled carbon nanotubes (MWCNTs) play a significant role in the nascent nanotechnology industry, due to their remarkable combination of mechanical, thermal, and electrical properties. These materials are specialty additives, reinforcing a diverse group of composites, including sporting goods, automobile body panels, and anti-static coatings. More than 25 commercial products incorporate MWCNTs, and production volumes exceed 500 tons per year . These volumes are expected to increase dramatically in the near future (3000 tons/year predicted by 2015) due to growing applications in electronics, data storage, defense, energy, aerospace, and the automotive industry . These new applications dictate higher performance and reliability and require tight control over the physical and chemical characteristics of the MWCNTs.
