Functionality in biological materials arises from complex hierarchical structures formed through self-assembly processes. Here, we report a kinetically trapped self-assembly of an elastic network of liquid droplets and its utility for tough and fast-acting underwater adhesives. This complex structure was made from a one-pot mixture of scalable small-molecule precursors. Liquid–liquid phase separation accompanied by silanol hydrolysis, condensation, and zwitterionic self-association yields a viscoelastic solid with interconnected liquid droplets. These hierarchical microstructures increase toughness and enable underwater adhesion for a range of substrates, offering a platform for robust adhesives for rapid underwater repair or emergency wound care.

用于水下粘合剂的弹性液滴网络

生物材料的功能源于自组装过程形成的复杂层次结构。在这里，我们报告了液滴弹性网络的动力学捕获自组装及其在坚韧且快速作用的水下粘合剂中的应用。这种复杂的结构是由可扩展的小分子前体的一锅混合物制成的。液-液相分离伴随着硅烷醇水解、缩合和两性离子自缔合，产生具有互连液滴的粘弹性固体。这些分层的微观结构提高了韧性，并使一系列基材能够在水下粘合，为快速水下修复或紧急伤口护理提供了坚固的粘合剂平台。
