We report a microwave-responsive supramolecular adhesive through the construction of cross-linked networks based on the coordination interaction between iron oxide nanoparticles and a catechol-based polymer. By microwave irradiation, the supramolecular adhesive can be quickly and selectively heated, causing strong adhesion for thermolabile substrates with negligible thermal damage. It can firmly and reversibly bond with diverse plastic substrates and shows an adhesion strength of 3.5 MPa toward glass fiber reinforced epoxy resin. Moreover, it displays excellent multiple reusability with almost no loss of adhesion strength after ten times reuse. Owing to the strong penetrability of microwave heating, it is anticipated that this kind of supramolecular adhesive shows great potential in microelectronics and fine chemical industry.

一种微波响应超分子粘合剂，可对不耐热基材进行强力粘合

我们报告了一种微波响应超分子粘合剂，通过基于氧化铁纳米粒子和儿茶酚基聚合物之间的配位相互作用构建交联网络。通过微波辐射，超分子粘合剂可以快速、选择性地加热，对不耐热基材产生很强的粘合力，而热损伤可以忽略不计。它能与多种塑料基材牢固、可逆地粘合，对玻璃纤维增强环氧树脂的粘合强度为3.5 MPa。此外，它还表现出优异的多次重复使用性，重复使用十次后粘合强度几乎没有损失。由于微波加热的强穿透性，预计这种超分子粘合剂在微电子和精细化工领域显示出巨大的潜力。
