Synthesis of dimpled and submicron-sized polymer particles of different morphologies using free micromixer

In this report, we propose a new method for synthesizing dimpled and submicron-sized polystyrene (PS) particles using a novel microfluidic device called the free micromixer (FMM). We could successfully synthesize dimpled and submicron-sized particles of various morphologies by controlling the concentration of PS and the temperature of the poor solvent used before mixing within the FMM. Formation of the particles can be attributed to the electrical charge of the polymer used for forming the particles.Graphical abstract
