Chemical Manufacture Of Nanostructured Materials
Tech ID: 10249 / UC Case 2002-079-0
Multi-walled carbon nanotubes have several potential applications in hydrogen storage, supercapacitors, and structural composites. However, most of these applications depend upon a reliable source of high-quality, inexpensive nanomaterials. Current carbon nanotube production methods, which use high-temperature arc-discharge, drive production costs prohibitively high and limit their use to only small-scale applications.
Scientists at the University of California have developed a novel process for the low-temperature formation of nanorods and nanoscrolls of various inorganic layered materials or compounds. In particular, this method can be used to form carbon nanoscrolls, a structure analogous to multi-walled carbon nanotubes.
This nanomaterials produced by this new UC process have applications in several areas, such as:
- Hydrogen storage;
- Electronic devices;
- Battery electrodes;
- High-strength structural composites.
The new UC technology provides the following benefits:
- Allows low-temperature, efficient nanomaterial production;
- Process can be applied to a variety of layered materials including graphite;
- Produces nanotube-like structures that provides a large accessible surface area.
