AbstractDevelopment of supramolecular adhesives with strong tolerance to extreme conditions has emerged as an important research area. In this study, by balancing supramolecular interactions such as hydrogen bonding interactions, electrostatic interactions, π–π stacking interactions, and cation‐π interactions, we designed and prepared a series of two‐component supramolecular adhesives derived from small organic molecules. Highly efficient interfacial adhesion with maximum adhesion strength of ≈10.0 MPa was realized on various surfaces in air, organic solvents, or liquid nitrogen. Owing to balanced supramolecular interactions, water participation prolonged and increased the tolerance of the adhesives in extreme environments. We demonstrate that the combination of imidazole‐based ionic liquids and phenols can be applied for various interfacial adhesions, thereby aiding the development of next‐generation adhesives capable of adapting to various extreme conditions in a controlled manner.
摘要 开发对极端条件具有较强耐受性的超分子粘合剂已成为一个重要的研究领域。本研究通过平衡氢键相互作用、静电相互作用、π-π堆积相互作用、阳离子-π相互作用等超分子相互作用,设计制备了一系列由小分子有机物衍生的双组分超分子粘合剂。在空气、有机溶剂或液氮中,在各种表面上实现了高效的界面粘附,最大粘附强度≈10.0 兆帕。由于平衡的超分子相互作用,水的参与延长并提高了粘合剂在极端环境下的耐受性。我们的研究表明,咪唑类离子液体与苯酚的结合可用于各种界面粘合,从而有助于开发能够以可控方式适应各种极端条件的下一代粘合剂。
