Aqueous foam stabilized by plate-like particles in the presence of sodium butyrate

摘要: The addition of salt promotes the adsorption layered double hydroxide (LDH) particles onto air-water interface, but stable foams cannot be prepared from LDH dispersions at all concentration NaCl or sodium acetate. We generated using positively charged plate-like in presence butyrate. effects adding butyrate to on particle zeta potential, behavior and modified interface were studied. At a fixed concentration, trace amount maximizes flocculation aqueous dispersion. Foams under this condition dispersion are most coalescence halt completely disproportionation. Also, size bubbles is smallest. when drying 80 degrees C with little change size. Laser-induced fluorescent confocal micrographs scanning electron microscopy observations clearly confirm foam surfaces, armored by an interfacial multilayer.
