“…9 However, methanol is not suitable for these acid-sugar adhesive materials as it gradually destroys the adhesion effects, which can be ascribed to hydrogen bond formation between methanol and acid-sugar polymeric structures. 11,38 Meanwhile, due to the water-soluble properties and hydrogen bond formation of acid-sugar adhesives, adhesion applications under water were not realized. To realize adhesion behavior under water, it is possible to prepare supramolecular adhesives from water-insoluble monomers.…”

“…[6][7][8][9] However, water can be easily removed from the sugar-water supramolecular polymeric systems during the practical adhesion process, thus leading to a significant attenuation of adhesion strength or adhesion effect. 10,11 With the rapid development of artificial polymeric adhesives in the past century, natural adhesives were no longer the research focus of modern adhesives. [12][13][14][15][16] In addition, the relatively weak adhesion capacities and the presence of water become obvious disadvantages, hindering the functionalization of sugar adhesives.…”

Natural adhesives have been widely replaced by industrial adhesives made from petroleum-based products. Compared with that of traditional natural adhesives, modern industrial adhesives show improved adhesion performance. However, the drawbacks of modern adhesives, including toxicity and nonbiodegradability, drive the need for new and high-performance adhesive materials from renewable and biocompatible natural feedstock. In this study, a new family of acid-sugar adhesive materials exhibiting excellent and long-term adhesion effects was developed inspired by the concept of deep eutectic solvents (DESs). The supramolecular polymerization between natural sugars and acids gave rise to both strong cohesion and adhesion properties. Moreover, high resistance to organic solvents is an advantage of acid-sugar supramolecular adhesive materials. This study not only dramatically expands the applications of DESs but also sheds light on the development of supramolecular adhesive materials as promising alternatives to polymeric adhesives.

“…Recently, extensive efforts have been expanded to enhance the performance of PSAs for both mechanical properties and stretchability simultaneously by the introduction of dynamic networks as energy-dissipating sacrificial linkages. The prevalent approaches for developing dynamic networks include dynamic noncovalent bonds (hydrogen 11,15 or coordinate bonds 19 ), dynamic covalent chemistry, [20][21][22][23] supramolecular interaction, [24][25][26][27][28][29][30] and double or triple networks. [31][32][33][34][35] In particular, supramolecular polymers are frequently applied to PSAs because of their stimuli-responsive characteristics, which should display a combination of both high fluidity and cohesive strength in the bonding and debonding processes.…”

Pressure-sensitive adhesives (PSAs) demand the ability to simultaneously improve toughness and adhesion. However, these requirements of PSAs have remained a great challenge because robust and recoverable characteristics are usually contradictory properties of PSAs. Dual cross-linking networks developed by incorporating dynamic noncovalent bonds into chemical cross-linking networks have the potential to mitigate these requirements in a wide variety of applications including adhesives, hydrogels, and elastomers. Herein, a facile approach to achieve dual cross-linking networks of acrylic PSAs with excellent mechanical properties and high-adhesive performance that integrate physically cross-linked networks into chemically cross-linked networks is proposed. Diurethane acrylic monomer-pentaerythritol ethoxylate (DAM-PEEL) groups were introduced into the acrylic PSA system through photopolymerization. The PSA/DAM-PEEL dual cross-linking networks led to the development of the chemically cross-linked networks for both PSA and DAM via covalent bonds and the physically cross-linked networks between the amide groups of DAM and the hydroxyl groups of PEEL via hydrogen bonds. Consequently, the PSA/DAM-PEEL dual cross-linking networks were able to simultaneously improve the modulus and stretchability. This design strategy for developing dual cross-linking networks of materials could offer potential applications for various adhesive-related applications.

Hydrogels used as strain sensors often rely on splicing tapes to attach them to surfaces, which causes much inconvenience. Therefore, to develop strain sensor hydrogels that possess both good mechanical properties and self‐adhesion is still a great challenge. Inspired by the multiple hydrogen bonding interactions of nucleobases in DNA, we designed and synthesized a series of hydrogels PAAm‐GO‐Aba/Tba/Aba+Tba comprising polyacrylamide (PAAm), graphene oxide (GO), acrylated adenine and thymine (Aba and Tba). The introduction of nucleobases helps hydrogels to adhere to various substrates through multiple hydrogen‐bonding interactions. It has also been found that the adhesive strength of hydrogels with nucleobases for hogskin increased to 2.5 times that of those without nucleobases. Meanwhile, these hydrogels exhibited good dynamic mechanical and self‐recovery properties. They can be directly attached to human skin as strain sensors to monitor the motions of finger, wrist, and elbow. Electrical tests indicate that they give precise real‐time monitoring data and exhibit good strain sensitivity and electrical stability. This work provides a promising basis from which to explore the fabrication of tough, self‐adhesive, and strain‐sensitive hydrogels as strain sensors for applications in wearable devices and healthcare monitoring.
