We have developed a mechanochemically responsive material capable of successively releasing small organic molecules from a cross-linked network upon repeated compressions. The use of a flex activated mechanophore that does not lead to main chain scission and an elastomeric polyurethane enabled consecutive compressions with incremental increases in the % mechanophore activation. Additionally, we examined the effect of multiple applications of compressive stress on both mechanophore activity and the mechanical behavior of the elastomeric matrix in which the mechanophore is embedded.
我们开发了一种机械响应材料，能够在反复压缩时从交联网络中依次释放小分子有机分子。使用不会导致主链断裂的柔性激活机械试剂和弹性聚氨酯，实现了连续压缩，并逐步增加机械试剂的激活百分比。此外，我们还研究了多次压缩应力对机械试剂活性和机械试剂嵌入的弹性基质机械性能的影响。
