Abstract

Abstract:

Functional microparticle materials have a wide range of applications in many fields due to their advantages of miniaturization and multi-functionality. As a new technical platform for materials fabrication, microfluidic technique shows unique creativity and superiority for controllable fabrication of functional microparticles. This review summarizes recent progress on controllable fabrication of diverse functional microparticles from microfluidic droplet templates, for use in fields such as chemical engineering, pharmaceuticals, energy storage, and environment. The rational design and controllable fabrication of functional microparticles, including porous spherical microparticles, compartmental spherical microparticles, and diverse nonspherical microparticles, by designing the structure and composition of microfluidic emulsion droplets are introduced. Strategies for the microparticles to achieve unique functions based on coupling of their microstructures and chemical compositions are discussed. Prospects on the future development of microfluidics for controllable fabrication of novel functional microparticles are provided.
