Multiscale toughening mechanisms in biomimetic tendon-like hydrogels.

ABSTRACT: Mimicking hierarchical structures found in nature, such as nacre and tendon, has led to remarkable successes in the creation of biomimetic materials with exceptional properties. The depth of knowledge derived from nature extends far beyond mere trial-and-error fabrication by providing deep insights into the toughening mechanisms that are integral to natural materials. A key challenge is understanding how these toughening mechanisms can be effectively translated into biomimetic materials. Here, we characterize the multiscale mechanical behavior of tendon-like fibrous hydrogels, unraveling the intricate toughening mechanisms at play across multiple scales-from dynamic molecular interactions and nanoscale fibril sliding, to anisotropic microscale characteristics and macroscopic performance-us
