摘要
In recent years, diverse stimuli-responsive allochroic materials have rapidly been developed, and smart materials with mechanochromic properties in particular have received increasing attention. This is because force fields have the advantage of being large and controllable compared to other stimulation modalities. Mechanochromic polymers mainly convert mechanical force signals into optical signals, which makes them suitable for applications in bionic actuators, encryption, and signal sensing. In this review, we summarize recent research progress in the design and development of mechanochromic polymers that are classified into two categories. The first category comprises those based on mechanophores that are physically dispersed in polymer matrices in the form of supramolecular aggregates. The second category comprises those based on mechanophores that are covalently linked to polymer networks. We focus on the working mechanisms of the mechanophores and their potential applications, which include damage monitoring and signal sensing.
