“…Cohesive rupture occurs during the peeling of the printed bilayer that PEE residues are left on the surface of DE after peeling (Fig. 3e), meaning that the interface is tougher than the bulk of PEE 40 . The strong interfacial bonding is mainly ascribed to the topological entanglements due to the similar chemistries between PEE and DE and the covalent interlinks due to the partial curing of each printing layer.…”

Stretchable ionotronics have drawn increasing attention during the past decade, enabling myriad applications in engineering and biomedicine. However, existing ionotronic sensors suffer from limited sensing capabilities due to simple device structures and poor stability due to the leakage of ingredients. In this study, we rationally design and fabricate a plethora of architected leakage-free ionotronic sensors with multi-mode sensing capabilities, using DLP-based 3D printing and a polyelectrolyte elastomer. We synthesize a photo-polymerizable ionic monomer for the polyelectrolyte elastomer, which is stretchable, transparent, ionically conductive, thermally stable, and leakage-resistant. The printed sensors possess robust interfaces and extraordinary long-term stability. The multi-material 3D printing allows high flexibility in structural design, enabling the sensing of tension, compression, shear, and torsion, with on-demand tailorable sensitivities through elaborate programming of device architectures. Furthermore, we fabricate integrated ionotronic sensors that can perceive different mechanical stimuli simultaneously without mutual signal interferences. We demonstrate a sensing kit consisting of four shear sensors and one compressive sensor, and connect it to a remote-control system that is programmed to wirelessly control the flight of a drone. Multi-material 3D printing of leakage-free polyelectrolyte elastomers paves new avenues for manufacturing stretchable ionotronics by resolving the deficiencies of stability and functionalities simultaneously.

“…Effective interfacial toughening strategies between hydrogels and elastomers have been extensively investigated by amplifying the adhesion work and designing effective interfacial energy dissipation strategies. [16,17] Chemically bonding tough hydrogel networks to an elastomer surface has secured a high adhesion energy to facilitate a robust interface, [16,18] even comparable to the interfacial toughness of human tendon-cartilage (Γ > 1000 J m −2 ). [19] Moreover, constructing/designing physical interactions, [20,21] interfacial interpenetrating networks, [12,22] interfacial phase separation, [23] and segment orientation mechanism [24] are also applied to toughen the interfaces.…”

Anchoring a layer of amorphous hydrogel on an antagonistic elastomer has potential applications in surface aqueous lubrication. However, the interfacial crack propagation usually occurs under continuous loads for amorphous hydrogel, leading to the failure of hydrogel interface. This work presents a universal strategy to blunt the interfacial cracks by designing a hydrogen bonds‐pinned entanglement (Hb‐En) structure of amorphous hydrogel on engineering elastomers. The unique Hb‐En structures is created by pinning well‐tailored entanglements via covalent‐like hydrogen bonds, which can amplify the delocalization of interfacial stress concentration and elevate the necessary fracture energy barrier within hydrogel interface. Therefore, the interfacial crack propagation could be suppressed under single and cyclic loads, resulting in a high interfacial toughness over 1650 J/m2 and an excellent interfacial fatigue threshold of 423 J/m2. Such a strategy universally works on blunting the interfacial crack between hydrogel coating and various elastomer materials with arbitrary shapes. The superb fatigue‐crack insensitivity at the interface allows for durable aqueous lubrication of hydrogel coating with low friction.This article is protected by copyright. All rights reserved
