The development of adhesives with switchable and programmable adhesion in both air water environments is highly desirable but still difficult to realize. Here, we have developed a smart hydrogel reversible behavior under thermal stimuli by introducing thermally responsive hydroxypropyl cellulose (HPC) polymer unit into the network. By alternately lowering raising temperature hydrogel, transition from sticky nonsticky state was achieved environments, wide switching range between high low adhesion, fast speed, durable efficiency. Accurate fine control dry wet strength can also be changing hydrogel. In addition performance, surface wettability, mechanical properties, optical transmission adapt programmed switched response change. exploiting its capacity, demonstrated as gripper for controllable capture release objects underwater environments. This study opens path design adhesives, materials, devices.

Abstract Developing epidermal electrodes that possess mechanic softness, tough adhesion, and high conductivity simultaneously is important but still remains challenging. Here, polyvinylpyrrolidone (PVP) introduced into poly(α‐thioctic acid) (PTA) to in situ generate ion‐clusters both PTA network on liquid metal particles (LMPs) surface, enhancing the mechanical strength toughness of PTA, as well its interfacial interaction with LMPs. As a result, poly(TA‐PVP)‐LMPs (noted PTPL) electrode reported softness (Young's modulus 175.86 kPa), adhesion (1604 J m −2 ), stretchability (>20 000%), rapid self‐healing, good biocompatibility. And attributed peel sintering LMPs, PTPL further exhibit electrical (26.19 mΩ sq −1 ) low skin impedance, providing signal‐to‐noise ratios (SNR 28.07 dB) accuracy monitoring multiple human electrophysiological signals. This work provides new strategy for balancing self‐adhesion, polymer materials fabrication.
