Ultrathin polymeric films have recently attracted tremendous interest as functional components of coatings, separation membranes, and sensors, with applications spanning from environment-related processes to soft robotics and wearable devices. In order to support the development of robust devices with advanced performances, it is necessary to achieve a deep comprehension of the mechanical properties of ultrathin polymeric films, which can be significantly affected by confinement effects at the nanoscale. In this review paper, we collect the most recent advances in the development of ultrathin organic membranes with emphasis on the relationship between their structure and mechanical properties. We provide the reader with a critical overview of the main approaches for the preparation of ultrathin polymeric films, the methodologies for the investigation of their mechanical properties, and models to understand the primary effects that impact their mechanical response, followed by a discussion on the current trends for designing mechanically robust organic membranes.
超薄聚合物薄膜作为涂层、分离膜和传感器的功能组件，近来引起了极大的关注，其应用范围涵盖从环境相关过程到软机器人技术和可穿戴设备等领域。为了支持开发具有先进性能的坚固器件，有必要深入理解超薄聚合物薄膜的机械性能，而这些性能会受到纳米尺度下的限域效应的显著影响。在这篇综述论文中，我们收集了超薄有机膜开发方面的最新进展，重点关注其结构与机械性能之间的关系。我们为读者提供了关于制备超薄聚合物薄膜的主要方法、研究其机械性能的方法以及理解影响其机械响应的主要因素的模型的批判性概述，随后讨论了设计机械坚固的有机膜的当前趋势。
