摘要

乳剂适用于各种工业和研究部门，这使得分析其流变行为至关重要。在本文中，我们讨论了液滴排列和变形之间的联系，以探索微观结构如何支撑乳液的流变行为。通过回顾前人的相关研究，我们讨论了液滴尺寸、体积分数、液滴间相互作用和界面性质对弹性模量、屈服应力、屈服应变和流动行为的影响。此外，我们详细阐述了浓缩和高浓度乳剂的弹粘塑性行为是如何由这些结构参数之间的相互作用所控制的，这些结构参数表明了弹性、塑性和粘性行为。最后，我们提出了在凝胶、排斥玻璃、吸引玻璃和压缩液滴状态下，热能密度、尺度液滴间相互作用和拉普拉斯压力如何决定可能的可恢复和不可恢复的应变机制。

Rheology and Structure of Emulsions

Emulsions are applicable across various industrial and research sectors, which makes analyzing their rheological behavior crucial. In this article, we discuss the links between droplet arrangement and deformation to explore how the rheological behavior of an emulsion is underpinned by microstructure. By reviewing our previous related investigations, we discuss the effects of droplet size, volume fraction, interdroplet interactions, and interfacial properties on the elastic modulus, yield stress, yield strain, and flow behavior. In addition, we elaborate how the elastoviscoplastic behavior of concentrated and highly concentrated emulsions is governed by the interplay among these structural parameters, indicating elastic, plastic, and viscous behavior. Finally, we suggest how the thermal energy density, scaled interdroplet interaction, and Laplace pressure determine possible recoverable and unrecoverable strain mechanisms in a gel, repulsive glass, attractive glass, and compressed droplet state.
