A straightforward method is presented for the preparation of nano- to micrometer-sized Janus disks with controlled shape, size, and aspect ratio. The method relies on cross-linkable ABC triblock terpolymers and involves first the preparation of prolate ellipsoidal microparticles by combining Shirasu porous glass (SPG) membrane emulsification with evaporation-induced confinement assembly (EICA). By varying the pore diameter of the SPG membrane, we produce Janus disks with controlled size distributions centered around hundreds of nanometers to several microns. We further transferred the disks to water by mild sulfonation of PS to polystyrene sulfonic acid (PSS) and verified the Janus character by subsequent labeling with cationic nanoparticles. Finally, we show that the sulfonated Janus disks are amphiphilic and can be used as efficient colloidal stabilizers for oil-in-water (O/W) emulsions.
