Tannic acid/clay hydrogel with time-dependent mechanical and adhesive performance enabled by molecular interaction evolution

The investigation on dynamic molecular mechanisms is of importance for developing smart materials for various applications. Herein, we report a dynamic tannic acid (TA)/clay hydrogel with time-dependent mechanical and adhesive performance, in which clay plays an important role in regulating the molecular interaction evolution of hydrogels. Specifically, TA mediated the assembly of clay to form networked hydrogels driven by TA-clay dynamic...
