Abstract Realizing the full potential of self‐healing materials in stretchable electronics necessitates not only low modulus to enable high adaptivity, but also toughness resist crack propagation. However, existing toughening strategies for soft have modestly improves mechanical dissipation near tip ( Г D ), and invariably compromise material's inherent softness autonomous healing capabilities. Here, a synthetic microporous architecture is demonstrated that unprecedently toughens softens without impacting their intrinsic kinetics. This structure spreads energy across entire material through bran‐new dissipative mode adaptable movement A which substantially increases fracture by 31.6 times, from 3.19 100.86 kJ m −2 , fractocohesive length 20.7 0.59 mm 12.24 mm. combination unprecedented (100.86 ) centimeter‐scale (1.23 cm) surpasses all previous records even exceeds those light alloys. Coupled with significantly enhanced (0.43 MPa) nearly perfect efficiency (≈100%), this robust ideal constructing durable kirigami wearable devices.

Abstract In the face of ubiquitous corrosion threats, development high-performance elastomer protective materials with active self-healing functions is extremely challenging and significant. We propose an approach by combining WPU GO to create multifunctional pearl layer structured polymers interface hydrogen bonds. By crosslinking polycaprolactone diol (PCL) chain a bond array, high mechanical strength, extensibility, elasticity, excellent damage resistance, healing properties was successfully synthesized. The exhibits remarkable properties, including tensile strength 39.89 MPa, toughness value 300.3 MJ m −3 , fracture energy 146.57 kJ −2 . enhanced resistance can be attributed decomposable array as well strain-induced crystallization PCL fragments, which effectively dissipate energy. Importantly, due reversibility bonding fractured easily heal restore its original when subjected heating at 50 °C. Moreover, photothermal enable biomimetic polymer coating achieve recovery after being irradiated NIR for 30 s. obtained highly oriented lamellar structure, thereby greatly enhancing physical barrier performance anti-corrosion performance. Electrochemical impedance spectroscopy (EIS) shows that modulus one order magnitude higher than blank coating. Additionally, scanning vibrating electrode (SVET) confirmed protection effect in 3.5 wt% NaCl solution were also reliable. This reliable presents revolutionary creating multi-functional, smart material harsh environments.

Poly(urethane-urea) elastomers (PUUEs) have gained significant attention recently due to their growing demand in electronic skin, wearable devices, and aerospace applications. The practical implementation of these necessitates many exceptional properties ensure robust safe utilization. However, achieving an optimal balance between high mechanical strength, good self-healing at moderate temperatures, efficient flame retardancy for poly(urethane-urea) remains a formidable challenge. In this study, we incorporated metal coordination bonds flame-retarding phosphinate groups into the design simultaneously, resulting high-strength, self-healing, flame-retardant elastomer, termed PNPU-2%Zn. Additional supramolecular cross-links plasticizing effects phosphinate-endowed PUUEs with relatively remarkable tensile strength (20.9 MPa), elastic modulus (10.8 efficiency (above 97%). Besides, PNPU-2%Zn possessed self-extinguishing characteristics limiting oxygen index (LOI) 26.5%. Such elastomer superior can resist both fracture fire hazards, providing insights development high-performance components applications devices.

The revolutionary self-healing function for long-term and safe service processes has inspired researchers to implement them in various fields, including the application of antimicrobial protective coatings. Despite great advances that have been made field fabricating polymers, their poor transparency trade-off between mechanical properties limit utility materials as transparent coatings wearable optical display devices. Considering compatibility blending process, our group proposed a self-healing, self-cross-linkable poly{(n-butyl acrylate)-co-[N-(hydroxymethyl)acrylamide]} copolymer (AP)-based coating combined with two types commercial cationic agents (i.e., dimethyl octadecyl (3-trimethoxysilylpropyl) ammonium chloride (DTSACL) chlorhexidine gluconate (CHG)), leading fabrication multifunctional modified compound film (AP/b%CHG)-grafted-a%DTSACL. first highlight this research is reactivity hydroxyl N-(hydroxymethyl)acrylamide side chains under thermal conditions facilitates "grafting to" process trimethoxysilane groups DTSACL form AP-grafted-DTSACL, yielding favorable stability, improvement hydrophobicity, enhancement strength.
