Graphitic Carbon Nitride Stabilizers Meet Microfluidics: From Stable Emulsions to Photoinduced Synthesis of Hollow Polymer Spheres

In this study, a special surface‐modified g‐CN is used to form stable Pickering emulsions. Using a PDMS‐based microfluidic device designed for stable production of both single and double emulsions, it is shown that surface‐modified g‐CNs allow the manufacture of unconventionally stable and precise Pickering emulsions. Shell thickness of the double emulsions is varied to emphasize the robustness of the device and also to demonstrate the extraordinary stabilization brought by the surface‐modified carbon nitride used in this study. Due to the electrostatic stabilization also in the oil phase, double emulsions are centered. Finally, when produced from polymerizable styrene, hollow polymer microparticles are formed with precise and tunable sizes, where g‐CN is utilized as the only stabilizer and photoinitiator.
