When one brings “polymeric materials” and “mechanical action” into the same conversation, the topic of this discussion might naturally focus on everyday circumstances such as failure of fibers, fatigue of composites, abrasion of coatings, etc. This intuitive viewpoint reflects the historic consensus in both academia and industry that mechanically induced chemical changes are destructive, leading to polymer degradation that limits materials lifetime on both macroscopic and molecular levels. In the 1930s, Staudinger observed mechanical degradation of polymers, and Melville later discovered that polymer chain scission caused the degradation. Inspired by these historical observations, we sought to redirect the destructive mechanical energy to a productive form that enables mechanoresponsive functions.

高分子机械化学：从破坏性到生产力

当人们将“聚合材料”和“机械作用”带到同一对话中时，此讨论的主题可能自然而然地集中在日常情况下，例如纤维的破坏，复合材料的疲劳，涂层的磨损等。这种直观的观点反映了历史在学术界和工业界都一致认为，机械诱导的化学变化具有破坏性，导致聚合物降解，从而限制了材料在宏观和分子水平上的寿命。在1930年代，施陶丁格（Staudinger）观察到了聚合物的机械降解，梅尔维尔（Melville）后来发现聚合物的断链导致了降解。受这些历史观察的启发，我们试图将破坏性的机械能转换为能够产生机械响应功能的生产形式。
