A method for growing high aspect ratio filaments comprising ultra-long vertically aligned carbon nanotube arrays

Advantages Robust method for producing SWNT arrays with high aspect ratios High Yields Filament length and diameter can be controlled by changes in growth conditions Aligned SWNT arrays impart improved properties to composite materials Minimum post-growth processing required

The Technology Ultra-long aligned carbon nanotube arrays with aspect ratios >100 are produced via a hot filament chemical vapor deposition technique on nano-structured alumina substrates. Typical yields of > 400% SWNT mass per unit mass of substrate are achieved as compared to ~30% for production of entangled SWNTS using existing processes

Potential Applications Direct spinning of carbon nanotube fibers Electronic applications Enhancement of properties of thin transparent films and ribbons
