In conventional double network (CDN) hydrogels, dense chemical cross-linking in the first frequently induces structural imperfections, resulting significant energy dissipation and substantial hysteresis under stress. To improve uniformity, spatial heterogeneities can be minimized by introducing mobile cross-linking, which facilitates creation of a more homogeneous network. Herein, we employed polymerization-induced entanglements (PIEs) strategy to tune from traditional net-like fabric-inspired topology, simultaneously promoting greater chain entanglement with second This innovative approach enables PIEs DN hydrogels exceptional performance, including significantly reduced (0.15), high tensile strength (1.25 MPa), excellent toughness (5800 J/m2), overcoming long-standing trade-off between observed CDN offering insights avenues for expanding hydrogel applications.

Interest in developing new, effective materials for emergency hemostasis and wound healing is steadily increasing, particularly use emergency, surgical, military situations. Hydrogels, with their unique retention, swelling, biocompatibility properties, have emerged as essential therapy. This review provides a comprehensive examination of recent hydrogel applications acute medical scenarios, including hemostasis, management, drug delivery, soft tissue replacement, engineering. We discuss the physicochemical properties that make hydrogels suitable rapid response situations, such tunable mechanical strength, adhesiveness, responsiveness to environmental stimuli, ability encapsulate release therapeutic agents. Additionally, article explores advancements smart self-healing antimicrobial providing insights into potential revolutionize care increase survival rates both civilian applications. Through critical evaluation current clinical trials practical deployments, this highlights successes challenges faced integrating protocols, roadmap future research development dynamic field.

The effect of the presence guar gum (0-0.75 wt%) in a thermo-responsive triple-network (TN) PVA/TA/PVA-MA-g-PNIPAAm hydrogel (PVA: polyvinyl alcohol; MA: methacrylate, PNIPAAm: poly-N-isopropyl acryl amide; TA: tannic acid) with respect to structural, mechanical, and viscoelastic properties was mapped. A comprehensive analysis, using large-amplitude oscillatory shear (LAOS), SEM imaging, XRD, mechanical analysis revealed that enhances crystallinity (up 30% at 0.75 wt%), which goes along strain hardening. achieved superior performance concentration 0.5 wt% 40% increase shear-thickening, an enhanced tolerance nonlinear regimes, good robustness (maximum elongation break 500% stress 620 kPa). exhibited also thermal response (equilibrium swelling ratio changed from 8.4 5 °C 2.5 50 °C) excellent cycling dimensional stability. Higher concentrations reduce structural resilience, leading brittle hydrogels lower extensibility
