CNT MicroArrays Grown on NanoFlake Substrates
- 详细技术说明
- CNT Microarrays Grown on Nanoflake Substrates A method for growing high aspect ratio filaments comprising ultra-long vertically aligned carbon nanotube arrays
- *Abstract
-
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
