Higher organisms as well as medical and technological materials exploit mineral-polymer interactions, however, mechanistic understanding of these interactions is poorly constrained. Dynamic force spectroscopy can probe the free energy landscape of interacting bonds, but interpretations are challenged by the complex mechanical behavior of polymers. Here we restate the difficulties inherent to applying DFS to polymer-linked adhesion and present an approach to gain quantitative insight into polymer-mineral binding.
高等生物以及医疗和技术材料都利用了矿物质-聚合物相互作用，但对这些相互作用的机械理解还受到很大限制。动态力谱学可以探测相互作用键的自由能景观，但聚合物的复杂力学行为对解释提出了挑战。在这里，我们重新阐述了将 DFS 应用于聚合物连接的粘附的固有困难，并提出了一种方法来深入了解聚合物-矿物质的结合。
