Abstract

Soft adhesive systems (SASs), which consist of a soft adhesive layer and/or soft adherends, have been extensively applied in advanced fields such as biomedicine, flexible electronics, and soft robotics. Understanding the fatigue failure of SASs is crucial for ensuring their structural safety and functional stability, as they are often subjected to fatigue loading. This paper systematically reviews the fatigue failure of SASs, aiming to provide a comprehensive understanding and contribute to the study of fatigue failure mechanisms and lifetime prediction of SASs. The review starts by introducing classical research methods for fatigue failure of adhesive systems, with a focus on total fatigue lifetime and fatigue crack growth (FCG). After summarizing the complexity of fatigue failure in SASs, it provides an overview of fatigue research for the three types of SASs: “soft interface”, “soft adherend”, and “soft-soft” adhesive systems. Then, the relations between the fatigue failure and energy dissipation of various SASs are specifically discussed noting that significant energy dissipation accompanying the cyclic deformation of SASs during fatigue loading can substantially affect the final fatigue failure of SASs. Finally, the current unresolved issues and challenges in this field are presented.

软粘合剂系统的疲劳失效：最新技术综述

软粘合系统（SAS）由软粘合层和/或软粘合剂组成，已广泛应用于生物医学、柔性电子和软机器人等先进领域。由于 SAS 经常承受疲劳载荷，因此了解 SAS 的疲劳失效对于确保其结构安全和功能稳定性至关重要。本文对 SAS 的疲劳失效进行了系统综述，旨在提供一个全面的理解，为 SAS 的疲劳失效机制研究和寿命预测做出贡献。综述首先介绍了粘合剂系统疲劳失效的经典研究方法，重点是总疲劳寿命和疲劳裂纹增长（FCG）。在总结了 SAS 疲劳破坏的复杂性后，综述了三种类型 SAS 的疲劳研究："软界面"、"软粘合剂 "和 "软-软 "粘合剂系统。然后，具体讨论了各种 SAS 的疲劳失效与能量耗散之间的关系，指出在疲劳加载过程中伴随 SAS 循环变形的大量能量耗散会对 SAS 的最终疲劳失效产生重大影响。最后，介绍了该领域目前尚未解决的问题和面临的挑战。

期刊介绍： Giant is an interdisciplinary title focusing on fundamental and applied macromolecular science spanning all chemistry, physics, biology, and materials aspects of the field in the broadest sense. Key areas covered include macromolecular chemistry, supramolecular assembly, multiscale and multifunctional materials, organic-inorganic hybrid materials, biophysics, biomimetics and surface science. Core topics range from developments in synthesis, characterisation and assembly towards creating uniformly sized precision macromolecules with tailored properties, to the design and assembly of nanostructured materials in multiple dimensions, and further to the study of smart or living designer materials with tuneable multiscale properties.
