“…[116] Moreover, hydrophobic eutectogels as underwater adhesives have also been recently put forward using polymerizable DESs. [117] Further researches are needed on hydrophobic ionogels available for practical marine environments. For instance, developing adhesives effective in the marine environment is still a challenge.…”

The emergence of hydrophobic ionogels composed of hydrophobic polymer matrices and hydrophobic ionic liquids has drastically broadened the applications of ionic devices, especially for underwater explorations. Compared with traditional ionogels, hydrophobic ones are capable of achieving long‐term stability in ambient and aqueous environments. In this review, the latest research developments of intrinsically hydrophobic ionogels are summarized, with particular emphases placed on the materials, mechanisms and applications. The basic issues about hydrophobic ionogels, including the material systems, dynamic gelation bonds and network structures are elucidated. The up‐to‐date advent of the ambient/underwater applications of hydrophobic ionogels concerning adhesion, self‐healing, and sensing are comprehensively summarized. Special attention is paid to underwater scenarios considering the rapid development of marine explorations and the intrinsic properties of hydrophobic ionogels. Finally, the current challenges and immediate opportunities of this emerging yet fast‐developing research field are discussed.

“…The excellent adhesive ability was attributed to conformal contacts between the ionogel and adherends, the synergistic effect of multiple interfacial interactions and energy dissipation during the lap shear process. [43][44][45] The good compatibility between polymers and CCl-U was conducive to a flexible motion of the polymer chains, thus allowing the successful anchorage of the ionogel onto the adherends. Besides, due to the presence of abundant functional groups, strong interfacial interactions existed between the ionogel and adherend, including electrostatic interactions, hydrogen bond interactions, iondipole interactions and van der Waals interactions (Fig.…”

“…The presence of abundant groups, such as carbonyl group, benzene group, hydroxyl group and ionic group in hydrophobic DES gels could provide strong adhesion to different substrates by multiple interactions, including hydrogen bonding, ionic interaction, ion-dipole interaction, and hydrophobic interaction. 39 As shown in Figure 5a, the DES gel could tightly adhere on a series of different substrates, such as glass, metals, and plastics. The adhesive strength between the DES gel and different material surfaces was measured by the 180 peeling force method (Figure 5b).…”

Owing to the advantages of temperature resistance, low cost, and biocompatibility, deep eutectic solvent (DES)‐based ionic conductive gels have attracted increasing research interest for flexible devices in recent years. However, current DES gels are all based on hydrophilic DES, which tend to absorb a large amount of environmental moisture, resulting in gel softening and adversely affecting the durability of the device. In this work, we highlight for the first time that N,N‐dimethylacrylamide monomer, and the obtained polymer can form hydrogen‐bonding networks with hydrophobic DES, methyl trioctyl ammonium chloride/ethyl 4‐hydroxybenzoate (1:2), thereby obtaining a hydrophobic DES‐based gel through photo‐polymerization. The resultant DES gel displays high stretchability (~900%), toughness (341.14 kJ m−3), anti‐fatigue property (recovery after 500 compression cycles), desirable conductivity (0.12 mS cm−1), adhesiveness and high transparency (>90% visible light transmittance). Notably, the hydrophobic DES‐based gel absorbs only 2 wt% water but exhibits significant water‐induced stiffening after exposing in ambient air for 1 week. These properties lead to the successful realization of the DES gels as wearable sensors to precisely monitor human motion. This work may open new avenues for the development of hydrophobic DES‐based gel ionotronics with functional performance.
