Performance of the Janus particles. (a) Optical images of the Janus particle dispersed in water (1), toluene (2) and (3) the frozen paraffin (Tm=52–54 °C)-in-water emulsion stabilized with Janus particles. (b) A polarizing optical microscopy image and (c) scanning electron microscopy (SEM) image of the frozen paraffin emulsion droplets. (d) A magnified SEM image of the Janus particles armoring the surface of the frozen paraffin sphere, all of the hemispherical coarse sides of the particles face toward the aqueous phase.
