Janus particles (JPs), initially introduced as soft matter, have evolved into a distinctive class of materials that set them apart from traditional surfactants, dispersants, and block copolymers. This mini-review examines the similarities and differences between JPs and their molecular counterparts to elucidate the unique properties of JPs. Key studies on the assembly behavior of JPs in bulk phases and at interfaces are reviewed, highlighting their unique ability to form diverse, complex structures. The superior interfacial stability and tunable amphiphilicity of JPs make them highly effective emulsifiers and dispersants, particularly in emulsion polymerization systems. Beyond these applications, JPs demonstrate immense potential as coating materials, facilitating the development of eco-friendly, anti-icing, and antifouling coatings. A comparative discussion with zwitterionic polymers also highlights the distinctive advantages of each system. This review emphasizes that while JPs mimic some of the behaviors of small molecular surfactants, they also open doors to entirely new applications, making them indispensable as next-generation functional materials.
Janus粒子（JPs）最初作为软物质被引入，现已发展成为一类独特的材料，使其有别于传统的表面活性剂、分散剂和嵌段共聚物。本综述探讨了JPs与其分子对应物之间的异同，以阐明JPs的独特性质。综述了关于JPs在本体相和界面处的组装行为的关键研究，突出了它们形成多样、复杂结构的独特能力。JPs优异的界面稳定性和可调谐的两亲性使其成为高效的乳化剂和分散剂，特别是在乳液聚合体系中。除了这些应用，JPs作为涂层材料显示出巨大潜力，有助于开发环保、防冰和防污涂层。与两性离子聚合物的比较讨论也突出了每个体系的独特优势。本综述强调，虽然JPs模仿了一些小分子表面活性剂的行为，但它们也为全新的应用打开了大门，使其作为下一代功能材料不可或缺。
