Abstract: An approach is reported to the batch scale fabrication of a huge family of anisotropic particles of advanced form employing Janus emulsion as template. The emulsion is obtained by one-step mixing three liquids of a polymerizable monomer as one of the oil phases, of the other immiscible oil as second oil phase, and of the aqueous solution. Upon UV-induced polymerization, solid particles with anisotropic shape are formed by the removal of the immiscible oil. The morphologies of resultant particles change from crescent to moon simply by adjusting the relative amount of oils. Moreover, we also achieve the size control from the challenging range of micrometer down to nanometer with the topology remained, easily by tuning the emulsification energy. In addition, the described method is also useful in the synthesis of Janus particles with chemically distinct hemispheres by mixing two immiscible polymerizable monomers.
