通过各种薄膜技术在纳米尺度上操纵界面的能力为推进表面应用提供了太多的途径。这些材料包括具有显著抗生物污垢性能的表面以及具有可调节的物理和电子性能的表面。分子自组装是一种引人注目的表面修饰和修饰方法。表面科学家特别感兴趣的是硫酸盐-金系统，它是一种可靠的方法来产生改变金表面界面性质的模型薄膜单分子膜。尽管有广泛的兴趣，但使用混合吸附系统调节界面性质的努力经常导致表面分子的相分离区域具有随机的大小和形状，这取决于吸附物质的结构和化学组成。这篇专题文章重点介绍了新出现的产生混合薄膜界面的方法，不仅增强了有机薄膜的上述性质，而且还产生了自然界中从未观察到的界面成分。一个例子是由双齿吸附体和其他独特的头基结构形成的单分子层的发展，这些结构提供了必要的表面键合稳定性，以允许组装暴露出性质根本不同(即，相不相容或结构不相似)的链的混合物的界面，从而产生组成上相互冲突的界面。这篇专题文章还通过探索先前制作这种均匀混合界面的努力，试图传达薄膜形成方法与所产生界面的整体属性之间的关系。
The ability to manipulate interfaces at the nanoscale via a variety of thin-film technologies offers a plethora of avenues for advancing surface applications. These include surfaces with remarkable antibiofouling properties as well as those with tunable physical and electronic properties. Molecular self-assembly is one notably attractive method used to decorate and modify surfaces. Of particular interest to surface scientists has been the thiolate-gold system, which serves as a reliable method for generating model thin-film monolayers that transform the interfacial properties of gold surfaces. Despite widespread interest, efforts to tune the interfacial properties using mixed adsorbate systems have frequently led to phase-separated domains of molecules on the surface with random sizes and shapes depending on the structure and chemical composition of the adsorbates. This feature article highlights newly emerging methods for generating mixed thin-film interfaces, not only to enhance the aforementioned properties of organic thin films, but also to give rise to interfacial compositions never before observed in nature. An example would be the development of monolayers formed from bidentate adsorbates and other unique headgroup architectures that provide the surface bonding stability necessary to allow the assembly of interfaces that expose mixtures of chains that are fundamentally different in character (i.e., either phase-incompatible or structurally dissimilar), producing compositionally "conflicted" interfaces. By also exploring the prior efforts to produce such homogeneously blended interfaces, this feature article seeks to convey the relationships between the methods of film formation and the overall properties of the resulting interfaces.
