“…[4,[23][24][25] For example, DOPA ligands are known to bind to different surfaces through metal-coordination, hydrogen bonding, pi-stacking, and hydrophobic associations. [26,27] It has also been demonstrated that the introduction of pendant DOPA ligands on polymer network backbones increase adhesion to metal-oxide surfaces, [4,14,18,[28][29][30][31] where enhancements in adhesion are the result of these transient interactions acting across interfaces. [4,8,[32][33][34][35][36] Further, the adhesion between two surfaces grafted with DOPA-functionalized brushes can also increase in the presence of metal ions due to ligand bridging.…”

This has further inspired the creation of supramolecular networks where metal-coordination complexation is the sole crosslinking mechanism. These fully transient, musselinspired hydrogels typically comprise multiarm polymers, end-functionalized with metal-coordinating ligands, such as His or DOPA, with metal ions serving as the crosslinking sites. [2,[20][21][22] Both His and DOPA are bidentate ligands that can coordinate with metal ions in either tris-, bis-, or mono-modalities, or are left free (unbound) (Figure 1a). [2,4] The tris-and bis-modalities serve as crosslinking sites to create a percolated transient hydrogel network, while the mono-modality and free ligands do not support network formation. To coordinate with metal ions, ligands must be deprotonated, and the concentration of available deprotonated ligands relative to the concentration of available metal ions determines the distribution of ligand coordination modalities at equilibrium within the network.

“…Some current studies report the fabrication of self-healable nanocomposites based on blends of PUs and organic or inorganic nano- or micro-particles [ 25 , 26 , 27 , 28 ]. Other studies have shown that the incorporation of adequately functional polymers or other compounds (for instance, poly(dopamine methacrylamide) [ 29 ], polycaprolactone [ 30 ], tannic acid [ 31 ]) as the dispersed phase in polyurethane matrices leads to self-healable composites. In such systems, self-healing is based on hydrogen bonding, van der Waals forces, hydrophobic interactions, thermo-induced healing, etc.…”

Self-healing materials and self-healing mechanisms are two topics that have attracted huge scientific interest in recent decades. Macromolecular chemistry can provide appropriately tailored functional polymers with desired healing properties. Herein, we report the incorporation of glycidyl methacrylate-based (GMA) copolymers in waterborne polyurethanes (WPUs) and the study of their potential healing ability. Two types of copolymers were synthesized, namely the hydrophobic P(BA-co-GMAy) copolymers of GMA with n-butyl acrylate (BA) and the amphiphilic copolymers P(PEGMA-co-GMAy) of GMA with a poly(ethylene glycol) methyl ether methacrylate (PEGMA) macromonomer. We demonstrate that the blending of these types of copolymers with two WPUs leads to homogenous composites. While the addition of P(BA-co-GMAy) in the WPUs leads to amorphous materials, the addition of P(PEGMA-co-GMAy) copolymers leads to hybrid composite systems varying from amorphous to semi-crystalline, depending on copolymer or blend composition. The healing efficiency of these copolymers was explored upon application of two external triggers (addition of water or heating). Promising healing results were exhibited by the final composites when water was used as a healing trigger.

“…Modern functional adhesives oen face more complex application environments, which means that adhesives need increasingly complex properties and oen require multiple functions. [1][2][3][4][5] Numerous researchers have developed and prepared adhesives with underwater adhesion, [6][7][8][9][10][11] multiple substrate adhesion, [12][13][14][15][16] stretchability, 17,18 self-healing, 19 biosustainability, [20][21][22] moldability, 23 etc. However, this not only requires a more complex structure of the polymer but also means that the conditions and steps required for synthesis become more cumbersome.…”
