Abstract The design and synthesis of supramolecular self‐healing polymers with high healing efficiency excellent integrated mechanical properties is challenging due to conflicting attributes dynamic properties. Herein, this study introduces a concept, that is, “dynamic hard domains,” balance performance, strength, elastic recovery, at the same time obtain extreme toughness. essential features domains include: (i) noncrystallized loose structure, (ii) low binding energy mobility, (iii)...
Abstract We designed and synthesized a colorless transparent glassy polyurethane assembled using low‐molecular‐weight oligomers carrying large number of loosely packed weak hydrogen bonds (H‐bonds), which has glass transition temperature ( T g ) up to 36.8 °C behaves unprecedentedly robust stiffness with tensile Young's modulus 1.56±0.03 GPa. Fast room‐temperature self‐healing was observed in this polymer network: the broken (GPU) specimen can recover strength 7.74±0.76 MPa after healing for...
Soft self-healing materials are compelling candidates for stretchable devices because of their excellent compliance, extensibility, and self-restorability. However, most existing soft polymers suffer from crack propagation irreversible fatigue failure due to easy breakage dynamic amorphous, low-energy polymer networks. Herein, inspired by distinct structure-property relationship biological tissues, a supramolecular interfacial assembly strategy preparing composites with unprecedented...
Abstract Shape memory polymers (SMPs) have attracted significant attention and hold vast potential for diverse applications. Nevertheless, conventional SMPs suffer from notable shortcomings in terms of mechanical properties, environmental stability, energy density, significantly constraining their practical utility. Here, inspired by the structure muscle fibers, an innovative approach that involves precise incorporation subtle, permanent cross‐linking within a hierarchical hydrogen bonding...
Abstract Supramolecular plastics (SMPs) can be made mechanically robust, repairable, and recyclable, rendering themselves promising alternatives to their conventional predecessors address environmental concerns. However, dense accumulations of noncovalent bonds generally lead mechanical brittleness as well intolerance toward heat moisture. To resolve this issue, a simple strategy preparing high‐performance SMP by constructing highly dense, but irregular hydrogen‐bond networks with...
Aqueous zinc batteries are considered as a viable candidate for cost-effective and environmentally sustainable energy storage technology but severely hampered by the notorious dendrite growth parasitic reactions at anode side. Herein, we propose bifunctional colloidal electrolyte design that utilizes upconversion nanocrystals, i.e., NaErF4@NaYF4, solid additive to provide sustained release of functional metal fluoride ions, which can effectively improve reversibility Zn inhibit hydrogen...
The heterogeneity and continuous cracking of the static solid electrolyte interphase (SEI) are one most critical barriers that largely limit cycle life lithium (Li) metal batteries. Herein, we report a fatigue-free dynamic supramolecular ion-conductive elastomeric (DSIEI) for highly efficient dendrite-free anode. soft phase poly(propylene glycol) backbone with loosely Li+-O coordinating interaction was responsible fast ion transport. Simultaneously, quadruple hydrogen bonds (H-bonds) in hard...
Strong interaction force improves the mechanical properties of energetic composites, and plentiful dynamic H-bonds endue excellent crack-healing performance.
Variable stiffness materials have shown considerable application in soft robotics. However, previously reported often struggle to reconcile high stiffness, stretchability, toughness, and self-healing ability, because of the inherently conflicting requisite these properties molecular design. Herein, we propose a novel strategy that involves incorporating acid-base ionic pairs capable from strong crosslinking sites into dense robust hydrogen-bonding network construct rigid polymers with...

Improving photocatalytic activity is crucial for promoting hydrogen production. Element doping a feasible strategy to accelerate carrier separation and migration rate. Herein, simple one-pot hydrothermal process was used create In doped Sn3O4 composite photocatalyst. It demonstrated that the addition of considerably raises concentration oxygen vacancy, which provides more unsaturated active sites, thus regulating photocatalyst's electronic structure surface properties, efficiency. Meanwhile,...
