Supramolecular assembly and complexation is a powerful method to impart new functionalities to various organic compounds and is extensively used in biomedical, energy, and surface coating applications. Among the number of substances that can induce supramolecular assembly, phenolic species such as dopamine are widely utilized for synthesizing adhesive materials due to the richness of hydroxyl groups that can drive the formation of hydrogen bonding. However, despite the strong adhesion capability of monomeric phenol, it lacks cohesive strength and rarely forms a supramolecular gel to secure its mechanical properties. In this study, to overcome this obstacle, we synthesized a supramolecular adhesive hydrogel by simply mixing PVP and tannic acid (TA), resulting in strong cohesive interactions by virtue of the larger molecular size of TA than monomeric phenols and reinforced molecular interactions attributed to the presence of galloyl groups with a high density. |
