How to integrate individual nanostructures into macroscopic thin films has become one of the most intriguing fields in nanoscience and nanotechnology due to the unique properties and important applications of these functional films. Since being discovered in 2004, oil-water interfacial self-assembly of nanostructures has become a novel strategy for fabrication of nanofilms. It is a powerful bottom-up approach for film fabrication due to the low cost and high efficiency, and is simple and universal for almost all low-dimensional nanostructures. In this article, we provide a critical review of the state-of-the-art research activities in this burgeoning self-assembly strategy. We first discuss the thermodynamic mechanism of the oil-water interfacial self-assembly, then the self-assembly of various low-dimensional nanostructures including nanoparticles, one-dimensional (1D) nanostructures, two-dimensional (2D) nanostructures at an oil-water interface developed so far to fabricate high-quality nanofilms. Finally, we present some progress on the construction of functional nanofilm-based nanodevices from this novel strategy based on our research. We conclude this review with critical comments on advantages and the experimental challenges, and further propose the future research and development of this self-assembly strategy for nanodevice construction (105 references).
如何将单个纳米结构集成到宏观薄膜中，由于这些功能薄膜的独特性质和重要应用，已成为纳米科学和纳米技术中最引人关注的领域之一。自 2004 年被发现以来，纳米结构的油水界面自组装已成为制备纳滤膜的一种新策略。由于其低成本、高效率，它是一种强大的自下而上的薄膜制造方法，而且对于几乎所有低维纳米结构来说，它都简单且通用。在本文中，我们对这一新兴自组装策略的最新研究进展进行了批判性的回顾。我们首先讨论了油水界面自组装的热力学机制，然后讨论了迄今为止在油水界面上制备高质量纳滤膜的各种低维纳米结构（包括纳米粒子、一维（1D）纳米结构、二维（2D）纳米结构）的自组装。最后，我们根据我们的研究，介绍了基于这一新型策略构建基于功能纳米滤膜的纳米器件的一些进展。我们对该自组装策略在实验挑战方面的优缺点进行了批判性的评价，并进一步提出了该自组装策略在纳米器件构建方面的未来研究和发展方向（引用文献 105 篇）。
