Janus particles are particles composed of two compartmentalized phases, hydrophilic and hydrophobic. To synthesize Janus particles by seed swelling photopolymerization, monodisperse PS-co-PVAc seed particles were first synthesized by dispersion polymerization. Then, modified seed particles having a hydroxyl group (PS-co-PVA particles) were prepared through surface hydrolysis of the seed particles. Finally, Janus particles functionalized with a hydroxyl group (PS-co-PVA/PTA particles) were synthesized by swelling tetradecyl acrylate (TA) monomer and photopolymerization. The effects of polymerization parameters such as ethanol/water ratio and stabilizer, initiator and monomer content on Janus particle were investigated. Through this study, monodisperse Janus particles having a size of 2-5 μm were successfully synthesized depending on the size of the seed particles. |
