The mechanical properties of polymer gels devote to emerging devices and machines in fields such as biomedical engineering, flexible bioelectronics, biomimetic actuators, energy harvesters. Coupling network architectures interactions has been explored regulate supportive characteristics gels; however, systematic reviews correlating mechanics interaction forces at the molecular structural levels remain absent field. This review highlights engineering gel a comprehensive mechanistic understanding regulation. Molecular alters architecture manipulates functional groups/moieties level, introducing various permanent or reversible dynamic bonds dissipative energy. usually uses monomers, cross-linkers, chains, other additives. Structural utilizes casting methods, solvent phase regulation, mechanochemistry, macromolecule chemical reactions, biomanufacturing technology construct tailor topological structures, heterogeneous modulus compositions. We envision that perfect combination may provide fresh view extend exciting new perspectives this burgeoning also summarizes recent representative applications with excellent properties. Conclusions are provided from five aspects concise summary, mechanism, biofabrication upgraded applications, synergistic methodology.

Abstract As skin bioelectronics advances, hydrogel wearable devices have broadened perspectives in environment sensing and health monitoring. However, their application is severely hampered by poor mechanical self‐healing properties, environmental sensitivity, limited sensory functions. Herein, inspired the hierarchical structure unique cross‐linking mechanism of hagfish slime, a self‐powered supramolecular hereby reported, featuring high stretchability (>2800% strain), ultrafast autonomous capabilities (electrical healing time: 0.3 s), self‐adhesiveness (adhesion strength: 6.92 kPa), injectability, ease shaping, antimicrobial biocompatibility. It observed that embedding with highly hygroscopic salt LiCl hydrogel, not only showed excellent electrical conductivity but also presented favorable anti‐freezing water retention properties extremely cold environments natural settings. Given these attributes, served as multifunctional durable device sensitivity (gauge factor: 3.68), fast response time (160 ms), low detection limit, frequency sensitivity. Moreover, applicability this further demonstrated long‐term sensing, remote medical communication, underwater communication. Overall, findings pave way for sustainable development hydrogel‐based are self‐powered, durable, offer performance, adaptability, multi‐sensory capabilities.

The development of next generation soft and recyclable materials prominently features dynamic (reversible) chemistries such as host-guest, supramolecular, covalent. Dynamic systems enable injectability, reprocessability, time-dependent mechanical properties. These properties arise from the inherent relationship between rate equilibrium constants (RECs) molecular junctions (cross-links) resulting macroscopic behavior networks. However, few examples explicitly measure RECs while exploring this connection material properties, particularly for polymeric hydrogel systems. Here we use covalent imine formation to study how single-point compositional changes in NH

Polyvinylidene fluoride (PVDF) latex nanoparticles serve as a versatile platform for surface modification due to their role precursors in PVDF manufacturing. However, the strong chemical stability and poor compatibility of present significant challenges effective modification. To address this, we developed method that facilitates through chain entanglement. By employing monomer swelling emulsion polymerization, poly(meth)acrylate (PA) monomers are incorporated into subsequently polymerized. Rheological properties transmission electron microscopy mapping confirmed entanglement between PA, indicating successful integration. This is efficient, straightforward, highly adaptable, making it well-suited large-scale industrial production.
