Abstract
There is provided methods and systems for disaggregation and deagglomeration of small scale materials such as carbon nanotubes by cavitation of a treatment substance. The treatment substance may be a substance such as CO2 which is capable of undergoing phase changes. Systems must be capable of withstanding high pressures, and cavitation may be done by ultrasound, mechanical agitation, injection of a jet stream, or other methods. Materials treated via the methods of the invention may be removed without the use of chemical surfactants or other chemical modification means, and may be further used in a battery.
Claims17
A method for dispersion of small-scale materials, the method comprising:
- placing a small-scale material powder into a treatment chamber;
- introducing a treatment substance into the treatment chamber, the treatment substance being capable of undergoing cavitation, wherein the treatment substance comprises carbon dioxide;
- and
- cavitating the treatment substance, wherein said cavitating causes dispersion of the small-scale material.
