Abstract Development of a universal stretchable ionic conductor coating on insulating substrates, irrespective surface chemistry and substrate shapes, is immense interest for compliant integrative large‐area electronics but has proved to be extremely challenging. Existing methods relying either the concurrent deposition polymerizing precursors or divided formulation painting processes both suffer from several limitations in terms adhesion, dehydration, processability, pre‐treatment. Here an ionogel paint that readily prepared concentration‐induced autonomous ring‐opening polymerization natural small molecule—α‐thioctic acid (TA) at ambient conditions reported. The presence liquid prevents polyTA further depolymerization via forming COOH···OS hydrogen bonds, resulting ultra‐stretchable ionogels with widely tunable mechanical conductive properties, self‐healability, as well tissue‐like strain adaptability. Moreover, owing its adhesion adjustable rheology, can directly coated diverse substrates arbitrary shapes (including porous materials, 3D printed frames, elastic threads) render them conductivity. Applications ionogel‐coated skin‐like highly sensitive durable large‐strain sensors are demonstrated, suggesting paint's great potential emerging soft electronics.

Abstract Swelling is ubiquitous for conventional hydrogels but not favorable many situations, especially underwater applications. In this study, an anti‐swelling and mechanically robust polyacrylic acid (PAAc)/gelatin composite hydrogel reported with a rapid gelation process (10 1 s) under mild conditions via the synergy of MXene‐activated initiation zirconium ion (Zr 4+ )‐induced cross‐linking, without requirement external energy input. The MXene found efficient to activate chain initiation, while Zr prone indispensable facilitating cross‐linking formed polymer chains. resulting exhibits integration exceptional properties high mechanical performance at room temperature, thanks dense hydrogen bonds between PAAc gelatin chains that enable upper critical solution temperature above temperature. Also, desirable electrical conductivity emerges in due simultaneous contribution , allowing stable signal output gel upon deformation underwater. As demonstration, communicator by harnessing as sensing module assembled, which capable wirelessly delivering messages decoder on ground Morse codes. This study provides exemplary way tough durable
