Abstract
Provided are emulsions and foam compositions that include patchy particles having at least two different surface chemistries, such as Janus particles. Also provided are methods of stabilizing emulsions and foam compositions by adding patchy particles to such emulsions or foam compositions during the process of forming such emulsions or foam compositions or after formation thereof. Further provided are methods of controlling droplet size in an emulsion or foam composition by adding patch particles having at least two different surface chemistries to the emulsion or foam composition. Additional embodiments are disclosed.
Claims28
An emulsion comprising patchy particles comprising at least a first surface and a second surface, the first surface having a different surface chemistry than the second surface.

A method of stabilizing an emulsion or foam composition comprising adding patchy particles having at least two different surface chemistries to an emulsion or foam.
A method of controlling droplet size comprising adding patchy particles having at least two different surface chemistries to an emulsion or foam composition.
