颗粒稳定的Pickering泡沫的研究进展

The Study on Development of Pickering Foams Stabilized by Particles

摘要: 近年来，将纳米颗粒(NPs)添加到表面活性剂泡沫体系以提高泡沫体系的稳定性受到了广泛的关注。本文旨在回顾和总结近年来关于颗粒稳定泡沫的最新研究结果，分析纳米颗粒的大小、表面湿润性、浓度和与表面活性剂的协同作用等主要因素对泡沫的影响，并确定未来研究的方向。在本文中，首先介绍了泡沫的结构与性质，其次介绍了纳米颗粒提高泡沫稳定性的机理。最后通过回顾近几年的研究，讨论了颗粒大小、表面湿润性、浓度等因素对泡沫稳定性的影响，结果表明：纳米颗粒对泡沫稳定性的影响是由多种因素共同构成的，目前还没有办法确定和衡量某一种单一性质对泡沫稳定性的贡献，这可能将成为未来研究的主题。

Abstract: The addition of nanoparticles (NPs) to the foam systems including the surfactant to improve the stability of foams has received extensive attention for several years. This paper aims to review and summarize the latest research on particle-stabilized foams in recent years, analyze the effects of nanoparticles size, surface wettability, concentration and synergy with surfactants on the foams, and identify directions for future research. In this report, the structure and properties of the foams are firstly introduced, and then the mechanism that nanoparticles improve the stability of the foams is briefly introduced. Finally, some major factors such as particle size, surface wettability, and concentration on the foam stability are introduced and discussed through new findings in recent years. The results of the study show that the effects of nanoparticles on the stability of the foams are composed of a combination of factors, and there is currently no way to identify and measure the contribution of a single property to the stability of the foams, which may be a subject of future research.
