“…Natural phenomena have often served as an inspiration for designing new synthetic materials. In recent years, the extraordinary ability of marine mussels to attach to virtually all types of inorganic and organic surfaces has attracted particular attention 1 . Clues for such universal adhesion ability lie in the high content of catechol (L-3,4-dihydroxyphenylalanine, L-Dopa) as well as primary and secondary amines (lysine and histidine) in the mussel’s adhesive proteins, secreted at the mussel-substrate interface 2 .…”

New insights in polydopamine formation via surface adsorption

Polydopamine is a biomimetic self-adherent polymer, which can be easily deposited on a wide variety of materials. Despite the rapidly increasing interest in polydopamine-based coatings, the polymerization mechanism and the key intermediate species formed during the deposition process are still controversial. Herein, we report a systematic investigation of polydopamine formation on halloysite nanotubes; the negative charge and high surface area of halloysite nanotubes favour the capture of intermediates that are involved in polydopamine formation and decelerate the kinetics of the process, to unravel the various polymerization steps. Data from X-ray photoelectron and solid-state nuclear magnetic resonance spectroscopies demonstrate that in the initial stage of polydopamine deposition, oxidative coupling reaction of the dopaminechrome molecules is the main reaction pathway that leads to formation of polycatecholamine oligomers as an intermediate and the post cyclization of the linear oligomers occurs subsequently. Furthermore, TRIS molecules are incorporated into the initially formed oligomers.

“…6 Recently, smart adhesives inspired by mussel adhesive proteins containing catechol have been developed for their ability to bond to wet surfaces reversibly. 7,8 The interfacial binding of catechol to various surfaces is often based on H-bonding, electrostatic interactions, and coordination bonds. 9−13 The adhesive property of catechol is dependent on its oxidation state, which can be controlled by changing the pH.…”

“…A smart adhesive can be deactivated or reactivated in response to externally applied stimuli (e.g., pH, temperature, light), which has various applications in multiple fields (e.g., biomedical, structural joints, automotive industry, robotics). − However, most of the existing smart adhesives exhibit poor adhesion in a wet environment .

The feasibility of deactivating and reactivating a catechol-containing smart adhesive electrochemically while in direct contact with a nonconductive surface was explored in this work. The adhesive was coated over an aluminum mesh-attached poly(dimethylsiloxane) (AM-PDMS) substrate. The aluminum mesh served as an electrode to apply electricity through the adhesive. A silver (Ag) counter electrode was coated in the periphery of the adhesive–substrate interface to deactivate the adhesive attached to the nonconductive surfaces including glass and poly(methyl methacrylate) (PMMA) substrates. The deactivation of the adhesive was performed with the application of up to 20 V of applied electricity utilizing the Ag electrode as a cathode and the aluminum mesh as an anode. The adhesion strength of the adhesive toward nonconductive surfaces decreased by 98% after in situ application of electricity. The deactivation rate was tunable with the applied voltage level, exposure time to the applied voltage, surface area of the adhesive interface, and aluminum mesh size. The deactivated adhesive was reactivated electrochemically by reversing the electrode polarity up to 3 cycles utilizing catechol–boronate complexation chemistry.

“…Nevertheless, most reported adhesives suffer from either inadaptable interfacial adhesion in the rigid high-density-interaction systems or low bulk cohesion in the weak less-density-linkage networks. Although the relationship between interfacial and bulk properties can be theoretically balanced by leveraging a nature-inspired catechol group (an intriguing adhesive functionality with versatile noncovalent/covalent interacting sites), the performance of such adhesives is still limited by the easy oxidization of catechol chemistry. ,− Consequently, despite great efforts, designing underwater adhesives with superior interfacial and bulk properties for high-strength, long-term, and harsh-environment adhesion remains elusive, mainly owing to the lack of effective adhesive functionalities. Moreover, practical implementations of underwater adhesives highly prefer the scalable characters such as easy operation, low cost, environmental friendliness, and no need of extra stimuli, but the literature reported to date rarely incorporate them into one system.…”

Developing scalable and high-performance underwater adhesives is important in various biomedical and industrial applications. However, despite massive efforts, the realization of such adhesives remains a challenging task, as mainly imposed by the difficulty in balancing the interfacial and bulk properties via an efficient way.Here, we report a facile yet effective strategy to construct a novel underwater adhesive with multiple advantaged performances by virtue of heterocyclic chemistry. This adhesive is designed with the cooperation of a heterocycle-based versatile adhesive functionality and an eco-friendly hydrophilic matrix with cross-linkable sites, which allows water absorption to destroy hydration layer, diverse molecular interactions to enhance interfacial adhesion, and abundant covalent crosslinks to strengthen bulk cohesion. Such a rational design endows the adhesive with strong underwater adhesion (up to 1.16 MPa for wood and 0.36 MPa for poly(tetrafluoroethylene) (PTFE)), long-term durability (maintaining pristine strength even after 4 months), and harsh-environment stability (salt, acidic/alkaline, low/high-temperature solutions). This strategy is also generic to derive more adhesive formulas, which offers a new direction for designing the next-generation underwater adhesives with high performance and scalability for practical applications.
