“…With the increase of IP6 content, the pore wall becomes narrower, and the pore structure is affected by the IP6 content. With the addition of IP6, the introduction of anionic phosphate ions increases, thereby enhancing electrostatic repulsion among microstructures within the gel and resulting in a modification of pore wall thickness . As the IP6 content increases, the aperture gradually decreases.…”

Ionic hydrogels can change the number of transient ions at low pressure to promote ion migration, similar to the sensory mechanism of human skin. Reported ionic hydrogel sensors have multiple ion migration characteristics, which is not conducive to the precise regulation of ion transport. In this paper, a double cross-linked anionic polyelectrolyte hydrogel (CPAM-IP6) with negative channels and internal cations was prepared with the main components of methacrylic acid (MAA), acrylic acid (AA), sodium carboxymethylcellulose (CMC), and inositol hexaphosphate (IP6). The prepared hydrogels show a unique interconnected porous structure due to the regular arrangement of chemical and hydrogen bonds. IP6 has high hydrogen bonding density, which provides the hydrogels with tunable mechanical properties and a large amount of dissociable proton H + . Optimized hydrogels exhibit excellent electrical conductivity (∼22 mS/cm), high tensile strength (∼0.56 MPa), and high strain at break (∼1030%). It has a modulus similar to that of human skin (E = 0.09−0.22 MPa) and has strain-hardening properties. In addition, the resistance changes and voltage signals of the hydrogel under different force modes (tension and compression) are monitored by dual-mode sensing with a high sensitivity and stability. Hydrogels are expected to be used for motion monitoring and energy collection and have broad application prospects in intelligent medical treatment.

Lignocellulose‐mediated liquid metal (LM) composites, as emerging functional materials, show tremendous potential for a variety of applications. The abundant hydroxyl, carboxyl, and other polar groups in lignocellulose facilitate the formation of strong chemical bonds with LM surfaces, enhancing wettability and adhesion for improved interface compatibility. Beyond serving as a supportive matrix, lignocellulose can be tailored to optimize the microstructure of the composites, adapting them for diverse applications. This review comprehensively summarizes the fundamental principles and recent advancements in lignocellulose‐mediated LM composites, highlighting the advantages of lignocellulose in composite fabrication, including facile synthesis, versatile interactions, and inherent functionalities. Key modulation strategies for LMs and innovative synthesis methods for functionalized lignocellulose composites are discussed. Furthermore, the roles and structure–performance relationships of these composites in electromagnetic shielding, flexible sensors, and energy storage devices are systematically summarized. Finally, the obstacles and prospective advancements pertaining to lignocellulose‐mediated LM composites are thoroughly scrutinized and deliberated upon. This review is expected to provide basic guidance for researchers to boost the popularity of LMs in diverse applications and provide useful references for design strategies of state‐of‐the‐art LMs.
