Recently, we reported the discovery of “capillary foams”, a new class of stable foams obtained by frothing a suspension of colloidal particles in the presence of a small amount of oil. A detailed understanding of the foam formation and the effects of material and process parameters lays a foundation for the targeted development of capillary foams toward future applications, which may range from the fabrication of load-bearing, lightweight porous materials, to enhanced oil recovery, advanced froth flotation, wastewater treatment, and oil spill remediation.
