Janus particles are a unique class of multifunctional patchy particles combining two dissimilar chemical or physical functionalities at their opposite sides. The asymmetry characteristic for Janus particles allows them to self-assemble into sophisticated structures and materials not attainable by their homogeneous counterparts. Significant breakthroughs have recently been made in the synthesis of Janus particles and the understanding of their assembly. Nevertheless, the advancement of their applications is still a challenging field. In this Review, we highlight recent developments in the use of Janus particles as building blocks for functional materials. We provide a brief introduction into the synthetic strategies for the fabrication of JPs and their properties and assembly, outlining the existing challenges. The focus of this Review is placed on the applications of Janus particles for active interfaces and surfaces. Active functional interfaces are created owing to the stabilization efficiency of Janus particles combined with their capability for interface structuring and functionalizing. Moreover, Janus particles can be employed as building blocks to fabricate active functional surfaces with controlled chemical and topographical heterogeneity. Ultimately, we will provide implications for the rational design of multifunctional materials based on Janus particles.
Janus 粒子是一类独特的多功能的有缺陷粒子，在其相对的两侧结合了两种不同的化学或物理功能。Janus 粒子的不对称特性使它们能够自组装成复杂的结构和材料，而这些结构和材料是其同类均匀粒子无法达到的。最近在 Janus 粒子的合成和组装方面取得了重大突破。然而，它们的应用的发展仍然是一个具有挑战性的领域。在这篇综述中，我们强调了最近将 Janus 粒子用作功能材料的构建块的用途。我们简要介绍了制造 JP 的合成策略及其特性和组装，概述了现有的挑战。这篇综述的重点是 Janus 粒子在活性界面和表面中的应用。由于 Janus 粒子的稳定效率以及它们对界面结构和功能化的能力，活性功能界面得以创建。此外，Janus 粒子可用作构建块来制造具有受控化学和形貌异质性的活性功能表面。最终，我们将为基于 Janus 粒子的多功能材料的合理设计提供启示。
