The formation of spontaneous double emulsions is a peculiar phenomenon in emulsion systems. When compared to the traditional one-step and two-step methods for preparing double emulsions, spontaneous emulsification can not only steadily load uniform water droplets into an oil phase, but can also facilitate the preparation of emulsions with higher stability. However, the limited solubility of salts, which are typically used to modify osmotic pressure, in organic oils has inhibited the viability of this method for the preparation of W/O/W double emulsions. In this paper, a redox-driven spontaneous emulsification method is developed and investigated. Instead of employing oil-soluble salts, an oxidation reaction is implemented in the oil phase, which produces cation radicals and iodide counterions to generate osmotic pressure. Additionally, amphiphilic polymer chains are harnessed as stabilizers for the newly formed W/O interfaces. Various characterization methods have been used to elucidate the mechanism of both the oxidation reaction and the spontaneous formation of double emulsions.

氧化还原驱动的自发双乳液

自发双重乳液的形成是乳液体系中的一种特殊现象。与传统的一步法和两步法制备双重乳液相比，自发乳化不仅可以将均匀的水滴稳定地负载到油相中，而且可以促进制备稳定性更高的乳液。然而，通常用于调节渗透压的盐在有机油中的有限溶解度抑制了这种制备 W/O/W 双重乳液的方法的可行性。在本文中，开发和研究了一种氧化还原驱动的自发乳化方法。代替使用油溶性盐，在油相中进行氧化反应，产生阳离子自由基和碘化物反离子以产生渗透压。此外，两亲聚合物链被用作新形成的 W/O 界面的稳定剂。各种表征方法已被用于阐明氧化反应和双乳液自发形成的机理。
