Abstract
A method is provided for producing particles, such as nanoparticles. The method includes introducing an ionic liquid into a deposition chamber, and directing one or more material toward or depositing one or more materials onto the ionic liquid by physical vapor deposition to form nanoparticles in the ionic liquid.
Claims28
A method for producing particles, comprising:
- introducing an ionic liquid into a deposition chamber;
- and
- directing one or more materials toward the ionic liquid by physical vapor deposition to provide particles in the ionic liquid.
A method for producing nanoparticles, comprising:
- introducing an ionic liquid into a deposition chamber;
- evacuating the deposition chamber to form a vacuum in the deposition chamber of no greater than 7 microns of Hg;
- and
- sputtering one or more cathodes in the deposition chamber to direct one or more materials toward the ionic liquid to provide nanoparticles in the ionic liquid.

A method for coating an ionic liquid, comprising:
- introducing an ionic liquid into a deposition chamber;
- evacuating the deposition chamber to form a vacuum in the deposition chamber no greater than 7 microns of Hg;
- and
- sputtering one or more cathodes in the deposition chamber to direct one or more materials toward the ionic liquid to form a coating film on the ionic liquid.
1 more element
A composition, comprising:
- an ionic liquid;
- and
- particles deposited in the ionic liquid by physical vapor deposition.
An apparatus for making particles, comprising:
- a deposition chamber;
- and
- a vessel for an ionic liquid, the vessel configured to capture material as it is deposited by a physical vapor deposition process in the deposition chamber, the vessel including inlet and outlet ports for the transport of an ionic liquid into the vessel and/or extraction of particle containing ionic liquid from the vessel.
