Morphological evolution of the anisotropic composite particles at varied monomer/particle weight ratio: (A) 2:1; (B) 16:1; (C) Janus characteristics of the anisotropic particles. (a) Left: a decane-in-water emulsion stabilized with the Janus particle as shown in Figure (A); right: a water-in-decane emulsion stabilized with the Janus particle as shown in Figure (B); water/decane volume ratio is 2:1, and the particle/water weight ratio is 1:100; (b) Optical microscopy images of the decane-in-water emulsion; and (c) water-in-decane emulsion; (d) Left: immiscible toluene/water mixture; right: a water-in-toluene emulsion stabilized with the Janus particle as shown in Figure 5d. Water/toluene volume ratio is 2:1, and the particle/water weight ratio is 2:1000. Adapted with permission from [46]. Copyright 2012, American Chemical Society.
