| Abstract: | Functional microparticle materials are widely used in many fields due to their unique characteristics of miniaturization and diverse functions. The versatile emulsion droplets from microfluidics provide excellent and unique templates for innovative design and controllable fabrication of functional microparticles. For microfluidic emulsion-template synthesis of functional microparticles, investigation on the formation and evolution of their meso-scale structures, the relationship between the interficial meso-scale structures of droplets and the dynamic behaviors of droplets, and the relationship between the coupled mass transfer-reaction and the meso-scale structures of microparticles, are of significant importance for rational control of the structures of emulsion templates and innovative fabrication of functional microparticlers. This review summarizes the recent progress on regulation of meso-scale structures for microfluidic emulsion-template synthesis of functional microparticles. Two aspects are mainly involved, including: (1) In the process for controllable microfluidic generation of emulsion templates, the relationship between the aggregation meso-scale structures of amphiphilic molecules at droplet interface and the droplet dynamics regarding motion, engulfment, coalescence, and interface evolution, and their influence on control of the morphology, structure and composition of the emulsion droplets; (2) In the process for emulsion template synthesis of functional microparticles, the rational control of trans-interfacial mass transfer, reaction and their coupling on the meso-scale structures of functional microparticles. This review could provide scientific guidance for the efficient fabrication and performance enhancement of novel functional microparticles. |
