Abstract

Developing underwater adhesives that combine rapid curing, high adhesion strength, recyclability, and long-term durability remains a significant challenge. Here, we report a recyclable underwater adhesive (AMN) synthesized via one-pot UV-initiated copolymerization of acrylic acid (AA), acrylamide (AM), and N-benzylacrylamide (NBAM) in dimethyl sulfoxide (DMSO). The adhesive exploits synergistic hydrogen bonding, hydrophobic interactions, and π–π stacking to achieve strong and stable adhesion on various substrates. Under optimal conditions (monomer mass fraction 22%, NBAM dosage 65%, photoinitiator 5%, UV irradiation 3 h), the adhesive exhibits a shear adhesion strength of 235 kPa on polycarbonate (PC) substrates, reaching 200 kPa within 10 min. Notably, the adhesive can be reversibly disassembled in ethanol (100% dissolution within 7 h) while remaining stable in tap water for over 7 days. After five reuse cycles, 76% of the original adhesion strength (178.5 kPa) is retained. The adhesive also maintains stable performance on PC for 100 days. This work provides a green, solvent-responsive, and durable adhesive platform with promising applications in marine engineering, biomedical devices, and flexible electronics.

可回收的水下胶粘剂，快速固化，高强度，长期耐用

开发具有快速固化、高粘接强度、可回收性和长期耐久性的水下粘合剂仍然是一个重大挑战。本文报道了一种可回收的水下胶粘剂（AMN），该胶粘剂是由丙烯酸（AA）、丙烯酰胺（AM）和n -苄基丙烯酰胺（nam）在二甲亚砜（DMSO）中一锅共聚合成的。该粘合剂利用协同氢键、疏水相互作用和π -π堆叠来实现在各种衬底上的强而稳定的粘附。在最佳条件下（单体质量分数22%，nam用量65%，光引发剂5%，UVirradiation 3 h），该胶粘剂在聚碳酸酯（PC）基材上的剪切粘接强度为235 kPa， 10 min内达到200 kPa。值得注意的是，该粘合剂可以在乙醇中可逆分解（7小时内100%溶解），而在自来水中保持稳定超过7天。经过5次重复使用，其原有粘接强度（178.5 kPa）仍保持76%。胶粘剂在PC上也能保持100天的稳定性能。这项工作提供了一种绿色，溶剂反应，耐用的粘合剂平台，在海洋工程，生物医学设备和柔性电子产品中具有广阔的应用前景。
