Mechanoresponsive polymers have garnered significant attention in recent years, due to their great potential application in stress/strain sensing and damage warning. Several reviews of mechanochemistry have been published recently. In this review, we mainly focus on the most established mechanophore, spiropyran (SP), from an engineering perspective. We present a workflow for SP mechanochemistry, applications in various polymeric systems and impacting factors, as well as characterization techniques. Current limitations and future research directions are briefly highlighted in the end. This review aims to offer deep insight into polymer mechanochemistry and provide approaches to study other mechanophores using the example of SP mechanochemistry in polymers.

机械响应性聚合物由于其在应力/应变感测和损伤预警中的巨大潜在应用，近年来受到了广泛的关注。机械化学的一些评论最近已经发表。在这篇综述中，我们主要从工程的角度着眼于最成熟的机制螺吡喃（SP）。我们介绍了SP机械化学的工作流程，在各种聚合物系统和影响因素中的应用以及表征技术。最后简要介绍了当前的局限性和未来的研究方向。这篇综述的目的是提供对聚合物机械化学的深刻见解，并提供以聚合物中SP机械化学为例的研究其他机理的方法。
