Water-in-water(W/W) emulsions, which are only composed of aqueous phases, has been recently promising due to their advantages, such as eco-/bio-friendly properties and the controllable permeability of small molecules at the water-water interface. However, the water-water interface possesses a very low interfacial energy, compared to that of the oil-water interface, so that it is quite difficult to stabilize the interface using conventional particle stabilizer. For this reason, securing high stability of the W/W emulsion is a key issue in greatly expanding their applicability. In this study, the effect of the type of microspheres on the stability of W/W emulsions was thoroughly studied. We compared the stability of W/W emulsions with inorganic particles with that with polymeric particles, and as a result, it was confirmed that polymeric particles are adequate for stabilizing the W/W emulsions, according to the visualization of dispersed droplets using a fluorescence microscopy. |
