Abstract

Based on the irresistible inherent trade‐off between the mechanical and self‐healing performances of cross‐linked polyurethane materials, there is still an intractable challenge to design efficient self‐healing and tough elastomers, especially in flexible sensors. Herein, a tough, efficient self‐healing, and recyclable cross‐linked polyurethane elastomer (DTPU) was prepared by integrating oxime‐carbamate bonds and thiourethane bonds into the network. The extraordinary mechanical properties and self‐healing performances of DTPU elastomers were related to the synergistic effect of oxime‐carbamate bonds in the main chain and thiourethane bonds in the chemical cross‐linked sites. The existence of dynamic cross‐linked points not only optimized the mechanical properties of DTPU but also provided support for the reversible cleavage and formation of oxime carbamate bond, thus endowing DTPU with efficient self‐healing performance and recyclability. After self‐healing at mild temperatures for 6 h, the self‐healed DTPU elastomers had a tensile strength of 30.27 MPa and a self‐healing efficiency of 95.5%. After multiple hot‐pressing, the original mechanical strength of DTPU was restored to over 100%, exhibiting excellent recyclable characteristics. Additionally, strain sensors based on self‐healing flexible elastomers were fabricated by introducing conductive carbon nanotubes. The strain sensors maintained their electrical conductivity after 3 times self‐healing, demonstrating great potential in healable flexible electronics. [ABSTRACT FROM AUTHOR]

Abstract

Multi drug-resistant Gram-positive pathogens have become one of the most serious problems facing humankind today. To address this challenge, there is an urgent need to develop new antimicrobial agents that are different from conventional antibiotics. Here, a Ru-based compound bearing benzonitrile, [Ru(dtb)2(BZIL)2](PF6)2 (RuBZ), was synthesized and evaluated. In vitro antibacterial studies demonstrated that RuBZ could efficiently inhibit S. aureus in vitro, showing higher potency than most existing clinical antibiotics, with a minimum inhibitory concentration value of 0.78 μg mL−1. Importantly, RuBZ can effectively inhibit S. aureus from forming a biofilm and releasing hemolytic toxin. What is more, RuBZ exhibited synergistic effects when combined with four clinical antibiotics. Mechanism studies suggest that RuBZ kills bacteria by disrupting their cell membrane. In addition, RuBZ has low hemolytic toxicity and shows good anti-infective potency in two animal infection models. Above all, our study presented here indicates that the Ru-based compound containing a benzonitrile group shows good potential for use as a new anti-infective agent. [ABSTRACT FROM AUTHOR]
