反应性液体界面的界面张力及其影响

Interfacial tension of reactive, liquid interfaces and its consequences

Anaïs Giustiniani, Wiebke Drenckhan, Christophe Poulard

摘要:

不混溶液体的分散体,如乳液和聚合物共混物,是许多工业应用的核心,这使得对其性质(形态,稳定性等)的理解变得更加复杂。非常感兴趣。这些性质的广泛范围取决于界面现象,因此理解界面现象特别重要。在使用预制表面活性剂的非反应性稳定过程中,乳液和聚合物共混物中的界面张力行为在理论和实验上都得到了很好的理解。然而,在反应体系中的界面张力行为的这种描述,其中稳定剂是在原位产生的(并且作为许多体系的稳定途径是更有效的),尚未在社区中找到共识。在这篇评论中,我们比较了不同的理论已经开发的非反应性和反应系统,我们讨论了他们的能力,捕捉实验发现的行为。最后,我们解决的后果的反应性稳定过程中的全球乳液或聚合物共混物的形态和在界面尺度。

英文摘要:

Dispersions of immiscible liquids, such as emulsions and polymer blends, are at the core of many industrial applications which makes the understanding of their properties (morphology, stability, etc.) of great interest. A wide range of these properties depend on interfacial phenomena, whose understanding is therefore of particular importance. The behaviour of interfacial tension in emulsions and polymer blends is well-understood -both theoretically and experimentally -in the case of non-reactive stabilization processes using pre-made surfactants. However, this description of the interfacial tension behaviour in reactive systems, where the stabilizing agents are created in-situ (and which is more efficient as a stabilization route for many systems), does not yet find a consensus amongst the community. In this review, we compare the different theories which have been developed for non-reactive and for reactive systems, and we discuss their ability to capture the behaviour found experimentally. Finally, we address the consequences of the reactive stabilization process both on the global emulsions or polymer blend morphologies and at the interfacial scale.
