摘要
The hierarchical design of mesoscale structures in droplet templates determines the structure and functionality of the resultant microparticles.In this review,we summarize recent progress on the control of microfluidic emulsion templates for the synthesis of polymeric microparticles with desired functionality and internal structure.We introduce strategies for controlling the morphology and interfacial stability of emulsion templates.These strategies are based on manipulation of the mesoscale structure of amphiphilic molecules and nanoparticles at emulsion-droplet interfaces.We also discuss strategies for controlling the mesoscale structure of microparticles,which involve manipulating the interfacial mass-transfer and chemical reactions during template synthesis.We provide insight on the use of these strategies for the rational design and fabrication of polymeric microparticles with predictable internal structures and functionality at the single-particle level.
