Multilayer thin films have garnered intense scientific interest due to their potential application in diverse fields such as catalysis, optics, energy, membranes, and biomedicine. Here we review the current technologies for multilayer thin-film deposition using layer-by-layer assembly, and we discuss the different properties and applications arising from the technologies. We highlight five distinct routes of assembly—immersive, spin, spray, electromagnetic, and fluidic assembly—each of which offers material and processing advantages for assembling layer-by-layer films. Each technology encompasses numerous innovations for automating and improving layering, which is important for research and industrial applications. Furthermore, we discuss how judicious choice of the assembly technology enables the engineering of thin films with tailor-made physicochemical properties, such as distinct-layer stratification, controlled roughness, and highly ordered packing.
多层薄膜因其在催化、光学、能源、膜和生物医学等多个领域的潜在应用而引起了科学界的浓厚兴趣。在这里，我们综述了使用层层组装技术制备多层薄膜的当前技术，并讨论了这些技术所产生的不同性质和应用。我们重点介绍了五种不同的组装方法——沉浸、旋转、喷涂、电磁和流体组装——每种方法在组装层层薄膜时都具有材料和加工方面的优势。每种技术都包含了许多用于自动化和改进分层的创新，这对于研究和工业应用都很重要。此外，我们还讨论了如何明智地选择组装技术，从而能够工程设计具有定制物理化学性质的薄膜，例如独特的层状结构、可控的粗糙度和高度有序的堆积。
