Abstract:

The demand of biomimetic underwater adhesives in biomedical and engineering applications is getting larger and larger. However, most of the reported preparation methods of biomimetic adhesives usually require complex chemical coupling or modification, and expensive constructing motifs. In this study, we develop a simple and economical construction strategy for the preparation of underwater adhesives using low-cost procyanidins (PA) extracted from grape seed and commercial polyethylene glycol oligomers (PEG) as building blocks, and realize the formation of biomimetic adhesives initiated by hydrogen bonding interaction. The adhesive can adhere to different substrates in both air and underwater, and can be reused at least three times. In addition, the PA/PEG adhesives are easy to prepare, have good antibacterial activity and biocompatibility. The PA/PEG adhesives could be widely used for pharmaceutical applications due to simple preparation, reusability, broad spectrum adhesion and antibacterial activity.
