Ion conductive hydrogels (ICHs) have attracted great interest in the application of ionic skin because their superior characteristics. However, it remains a challenge for ICHs to achieve balanced properties high strength, large fracture strain, self-healing and freezing tolerance. In this study, strong, stretchable, antifreezing ICH was demonstrated by rationally designing multiphysically cross-linked network structure consisting hydrophobic association, metal-ion coordination chain entanglement among poly(acrylic acid) (PAA) polymer chains. The deliberately designed Brij S 100 acrylate (Brij-100A) micelle cross-linker can effectively dissipate energy endow with desirable stretchability. ability originates from reversible association micelles Fe3+-COO– coordination. After addition NaCl, chain-entangled physical caused salting-out effect both enhance mechanical strength promote electron transport. With synergy mental-ligand entanglement, PAA/Brij-100A/Fe3+/NaCl (PAA/BA/Fe3+/NaCl) exhibited tensile strain 1140%, 0.93 MPa toughness 3.48 MJ m–3. Besides, PAA/BA/Fe3+/NaCl conductivity 0.43 m–1 good resistance. based on showed sensitivity (GF = 5.29), wide range (0–950%), fast response time (220 ms) stability. Also, significantly prolong its service time, property broaden applicable temperature. This study offers new insight into design multifunctional wearable electronics.

Permanent polymer networks present an important sustainability challenge. Irreversible covalent crosslinks impart these materials excellent mechanical properties, thermal and chemical resistance, yet also render them difficult to repair recycle. Self-healing mechanisms can extend the lifetime of thermosets elastomers, improving their durability making lifecycle more sustainable. In addition extension, this paper reviews self-healing polymers from a holistic point view. The entire is critically assessed with reference green chemistry principles sustainable development. relation between chemistries aspects each phases are discussed, starting feedstocks, monomer functionalisation synthesis, processing manufacturing as well end-of-life considerations, i.e. recycling or (bio)degradation. review provides toolbox for development thermosets, elastomers composites. It utmost importance consider materials, derived products – by extension any material product. ability often related recyclability should primarily reduce amount new that necessary fulfill societal needs, extending maximizing reprocessing into products. Increasing healing efficiency number cycles improves overall environmental impact relative extended service lifetime. Renewable resources biomass, processes waste streams be first choice create polymers. Finally, biodegradability considered complementary scenario upon accidental loss environment, provided biodegradation does not start under prospected use conditions products, but postponed until contact stimuli in environment.

The design and synthesis of conductive hydrogels with antifreezing, long-term stable, highly sensitive, self-healing, reusable is a critical procedure to enable applications in flexible electronics, medical monitoring, soft robotics, etc. Herein, novel zwitterionic composite hydrogel possessing fast self-healing performance, water retention, adhesion was synthesized via simple one-pot method. LiCl, as an electrolyte antifreeze, promoted dissociate under the electrostatic interaction zwitterions, resulting high electrical conductivity (7.95 S/m) excellent antifreeze ability (-45.3 °C). Meanwhile, could maintain 97% initial content after exposed air (25 °C, 55% RH) for 1 week due presence salt ions. Moreover, active groups zwitterions form conformal between skin, which particularly crucial stable signal output sensor. dynamic borate ester bonds, group hydrogen bond different components achieve rapid (2 h, efficiency 97%) without any external intervention. Notably, developed PBAS-Li (poly(vinyl alcohol) Borax/acrylamide/zwitterionic-LiCl) not only succeeded sensitively detecting human motions but also precisely captured handwritings signals subtle pulse waves on neck wrist. above findings demonstrated great potential field electronic devices.
