摘要: A supramolecular approach was applied to the construction of adhesive materials with excellent temperature resistance and strong adhesion capacity. Supramolecular hot-molten glues were prepared from two small compounds, acrylic acid (A) and choline chloride (C), using a combination of molecular recognition (formation of supramonomers) and supramolecular polymerization (formation of cross-linked polymers). The coexistence of covalent poly(A) backbones and non-covalent crosslinker C units enabled the poly(A-C)s to display tough adhesion effects with long-term stability at high (150 degrees C, 5.18 MPa) and low temperatures (-196 degrees C, 9.52 MPa) without any additives. Real-time and quantitative monitoring of the adhesion behavior of poly(A-C)s was successfully realized over a wide temperature range of -80 to 150 degrees C, using a customized device that allowed for easy monitoring of the adhesion duration, attenuation, and failure. Importantly, adhesion failure was visualized and wirelessly alarmed.
