Abstract

In this work we developed a facile method to prepare water-oil Janus emulsions in situ with tunable morphologies by using a double-bore capillary microfluidic device. In addition, by combining the theory model and our liquids' properties, we propose a method to design the morphology of water-oil Janus emulsions. To systematically research Janus morphologies we combined the theory model and the fluids' properties. Under the model guidance, we carefully selected the liquids system where only the interfacial tension between the water phase and the continuous phase changed while keeping the other two interfacial tensions unchanged. Thus we could adjust the Janus morphology by changing the surfactant mass fraction in the continuous phase. In addition, with the double-bore capillary, we prepared water-oil Janus emulsions with a large flow ratio range. By adjusting the flow ratio and the surfactant mass fraction, we successfully prepared Janus emulsions with gradual morphology changes, which would be meaningful in fields that have a high demand for morphology designing of amphiphilic Janus particles.
