From: Charging and discharging of single colloidal particles at oil/water interfaces
Time evolution of single colloidal particles trapping at oil/water interfaces in absence or presence of a monovalent salt (NaCl) in the water phase.
Time evolutions of radius distribution functions (g(r)) of polystyrene microspheres (1.0 μm) trapping at an (a) octane/H2O interface or (b) an octane/10 mM NaCl interface as well as their bright-field images (c), where 5% isopropanol was used as the spreading solvent, colors represent time lapse. (d) Stability of polystyrene microspheres trapping at oil/water interfaces with presence of different amounts NaCl in the water phase ranging from 0.01 to 10 mM, where solid symbols in the shadow represent emerging of colloidal aggregates at oil/water interfaces.
