We introduce the synthesis method of monodisperse Janus particles which can control the phase compartment and the surface amphiphilicity. Using seeded swelling technique and photo-polymerization method, Janus particles with uniform size and shape were synthesized. Polystyrene (PS) seed particles were swollen by alkyl acrylate monomers with different alkyl chain lengths, and then the particles were polymerized using UV radiation. The Janus particles showed a morphology consisting of two phases which minimize the interfacial free energy due to the phase mismatch of poly(alkyl acrylate) chains on PS seed. We investigated the synthesis of Janus particles depending on alkyl acrylate monomers with different alkyl chain lengths. When tetradecyl acrylate (TA) monomer was used, the Janus particles were separated into two phases of PS and PTA. Moreover, the relative compartment range of the Janus particles could be precisely adjusted. This technique can be extended to non-spherical particles.
