以液滴模板法来制备颗粒材料，可通过对液滴以及颗粒界面介尺度结构的形成与反应的定向调控来实现对固体颗粒功能材料的高效制备和性能强化。深入研究液滴和固体颗粒界面介尺度结构与反应-扩散过程的相互关系及其定向调控规律，揭示反应与扩散过程的机制及其耦合，对于实现反应过程强化与理性调控具有重要的意义。本文主要介绍了液滴模板法制备颗粒材料过程中的介尺度结构调控的研究新进展，着重介绍了界面两亲分子聚集态介尺度结构对液滴形貌的定向调控及对液滴稳定性的影响、以及液滴界面传递与反应对颗粒材料介尺度结构的定向调控，以期为液滴模板法合成颗粒材料的反应过程强化与理性调控提供科学指导。
For particle materials fabricated by droplet-template syntheses, the efficient fabrication and function enhancement can be realized by rational control of the interfacial meso-scale structures of droplets and particles. Study on the relationship between the interfacial meso-scale structures of droplets and particles and the reaction-diffusion processes, and the investigation of the interconnection between reaction and diffusion, are of significant importance for intensification and rational control of the synthesis processes. This review summarizes the recent progress on control of meso-scale structures for droplet-template syntheses of particle materials, mainly focusing on control of droplet morphology and droplet stability via manipulation of the aggregation meso-scale structures of interfacial amphiphilic molecules, and on control of the meso-scale structure of particles via manipulation of mass-transfer and reaction at/across droplet interfaces. This review provides scientific guidelines for the intensification and rational regulation of reaction processes for droplet-template syntheses of particle materials.
