But that's still a far cry from commercialization. "Most materials at volume--say, a billion pounds "We can't get there shooting lasers at graphite blocks." per year or so--are less than $1.00 per lb," "We can't get there shooting lasers at graphite blocks." Commercial-scale production of fullerenes and nanotubes in kilogram-per-day amounts is still at least a year away. However, some industry pundits are already calling fullerenes and other materials--such as nanotubes, metals, and clays finding limited use in composite materials and coatings--the "mature" side of nanotechnology. Nanotechnology, including these nanoscale materials, is being touted as the next industrial revolution, with long-term and wide-ranging effects on many products and industries. The U.S. government goes as far as suggesting that in just another 10 to 15 years, nanotechnology will impact more than $1 trillion per year in products and services. However, to have a great impact, nanotechnology must not only yield expensive products for possible high-end applications, but also inexpensive products for large-volume uses. Meeting these market needs means overcoming some sizable technological challenges. THE DESIRED properties that nanomaterials must offer, such as both stiffness and toughness, are "contradictions" and thus often difficult to achieve in combination. Success is delivering the properties we need at the right price, and that price is low," he added. "You must also be able to make products quickly using low-cost starting materials." |
