Acylsemicarbazide is used to toughen a dynamic poly(disulfide) network by forming synergistic covalent and noncovalent crosslinkers. The resulting dry supramolecular network exhibits enhanced stretchability, mechanical strength and toughness while retaining dynamic reconfigurability.

Zirconium disilicide (ZrSi) ceramics have excellent physical and chemical properties and are employed in aerospace, energy, and chemical industries. Currently, the preparation and properties of ZrSi ceramics have been less studied. To comprehensively study the characteristics of ZrSi ceramics, in this study, dense bulk ZrSi ceramic samples are successfully prepared by the high-pressure-high-temperature (HPHT) sintering technique.

Ionic conductive hydrogels show promise for flexible sensors in wearables and e-skins, but balancing mechanical strength with high conductivity remains challenging. Herein, a triple-network ionic conductive hydrogel based on poly(acrylic acid) (PAA) was developed, synergistically reinforced by dissolved cellulose (dCel) and aramid nanofibers (ANF), with Al/Zn bimetallic ions serving as the conductive medium. Intriguingly, dCel was in-situ generated using the concentrated Al/Zn bimetallic salt solutions as the cellulose solvent, following the complete dissolution of the pulp fibers driven by the intensive ionic hydration of Al/Zn ions.

Acoustic transducers require films that demonstrate both toughness and fatigue resistance, presenting notable challenges when achieved through conventional nanoscale reinforcing strategies. Here, we found that the rib structure of a cicada's tymbal exhibits exceptional toughness and fatigue resistance, attributed to its unique architecture composed of alternating soft and stiff polymer layers. Inspired by this rib structure, we developed a robust artificial rib film (ARF) using a nanoconfined crystallization strategy that involves the deposition of soft polyethylene oxide and stiff phenol formaldehyde.

Polymerizable deep eutectic solvents (PDES) have recently emerged as a class of solvent-free ionically conductive elastomers and are considered among the most feasible candidates for next-generation ionotronic devices. However, the fundamental challenge persists in synergistically combining high mechanical strength, robust adhesion, reliable self-healing capacity, and effective antimicrobial performance within a unified material system capable of fulfilling the rigorous operational demands of next-generation ionotronic devices across multifunctional applications. Inspired by the hierarchical structure of spider silk, HCAG eutectogels composed of acrylic acid (AA), 2-hydroxyethyl acrylate (HEA), and choline chloride (ChCl) were successfully synthesized via a one-step photopolymerization method.
