Scars caused by skin injuries after burns, wounds, abrasions and operations have serious physical psychological effects on patients. In recent years, the research of scar free wound repair has been greatly expanded. However, understanding complex mechanisms healing, in which various cells, cytokines mechanical force interact, is critical to developing a treatment that can achieve scarless healing. Therefore, this paper reviews types mechanism formation healing process, current progress dual consideration prevention, some strategies for repair.

Abstract Elastomers are widely used in daily life; however, the preparation of degradable and recyclable elastomers with high strength, toughness, excellent crack resistance remains a challenging task. In this report, polycaprolactone‐based poly(urethane‐urea) elastomer is presented mechanical properties by optimizing arrangement hard segment clusters. It found that long alkyl chains chain extenders lead to small evenly distributed clusters, which beneficial for improving properties. Together multiple hydrogen bond structure stress‐induced crystallization, obtained exhibits strength 63.3 MPa, an toughness 431 MJ m −3 outstanding fracture energy 489 kJ −2 , while maintaining good recyclability degradability. believed holds great promise various application fields it contributes development sustainable society.

Abstract Advances in modern industrial technology continue to place stricter demands on engineering polymeric materials, but simultaneously possessing superior strength and toughness remains a daunting challenge. Herein, pioneering flexible cage‐reinforced supramolecular elastomer (CSE) is reported that exhibits superb robustness, tear resistance, anti‐fatigue, shape memory properties, achieved by innovatively introducing organic imide cages (OICs) into networks. Intriguingly, extremely small amounts of OICs make the stronger, significantly improving mechanical (85.0 MPa; ≈10‐fold increase) (418.4 MJ m −3 ; ≈7‐fold increase). Significantly, cooperative effect gradient hydrogen bonds experimentally theoretically demonstrated as nodes, enabling more robust In short, proposed strengthening strategy adding effectively balances inherent conflict between material toughness, prepared CSEs are anticipated be served large‐scale devices such TBMs future.

Owing to their extensive application scope, elastomers that combine high strength and excellent self-healing efficiency have always attracted significant attention are still a contradiction. In this study, novel PU elastomer was prepared by combining rigid poly(amic acid) (PAA) chain segments 3,3-dithiodipropionic dihydrazide (DPH) containing sextuple hydrogen-bonding units disulfide bonds. The exhibited tensile of 50.1 MPa toughness 144.2 MJ/m3. PAA serve as framework, significantly enhancing the mechanical elastomer. Meanwhile, DPH with bonds enabled exhibit an 96.1% after 12 h at 80 °C. Additionally, strong reversible cross-linking arrays in endows it strength, ability, recyclability, allowing be recycled hot pressing dissolution.

Despite the recent rapid advancements in room-temperature self-healing waterborne polyurethanes, imparting fast ability while concurrently maintaining robust mechanical performance of polyurethanes remains a formidable challenge. Herein, we propose molecular structure design strategy for developing visible light-responsive, self-healing, and antibacterial polyurethane (DMZWPU) containing triple dynamic bonds diselenide bonds, multiple hydrogen Zn(II)–carboxylate coordination bonds. This innovative approach effectively balances tensile stress, fracture toughness, material. Thanks to synergy three resulting DMZWPU film demonstrates stress 40.32 MPa toughness 119.29 MJ/m3, respectively. Furthermore, based on characteristics dual induction trace ethanol light, damaged can recover more than 85% at room temperature within 2 h. These performances outperform those most currently reported self-healable polymers (healing efficiency >80%). Due combined action selenium zinc ions, DWZWPU exhibits excellent properties (sterilization rate 100% 24 h). Finally, emulsion is applied leather finishing processes, results show that coating folding resistance, wear function, as well enhanced water resistance dry friction resistance. In summary, this study provides novel perspective development with high temperature.
