空气中聚合物刷的基本原理和应用

摘要

几十年来，高密度、末端栓系聚合物形成了所谓的聚合物刷，激发了科学家们对其特性的理解，并将其应用于实际。虽然早期的研究主要集中在液体中的聚合物刷，但最近人们认识到，这些刷也可以应用于空气中。在这篇综述中，我们报告了在解开空气中刷子的基本概念方面的最新进展，例如它们的蒸汽膨胀和溶剂分配。此外，我们还概述了在空气中的大量应用（如传感、分离或智能粘合剂），其中电刷可能是关键部件。最后，我们通过确定悬而未决的问题和问题提供了一个展望，这些问题一旦解决，将为空气中刷子的大规模应用铺平道路。

Abstract

For several decades, high-density, end-tethered polymers, forming so-called polymer brushes, have inspired scientists to understand their properties and to translate them to applications. While earlier research focused on polymer brushes in liquids, it was recently recognized that these brushes can find application in air as well. In this review, we report on recent progress in unraveling fundamental concepts of brushes in air, such as their vapor-swelling and solvent partitioning. Moreover, we provide an overview of the plethora of applications in air (e.g., in sensing, separations or smart adhesives) where brushes can be key components. To conclude, we provide an outlook by identifying open questions and issues that, when solved, will pave the way for the large scale application of brushes in air.
