Summary: By introducing Cu-pyridine coordination, we have successfully fabricated a polyurethane elastomer with fast self-healing and enhanced mechanical properties. The mechanical properties of the elastomer are improved by increasing the coordination bonds and hydrogen bonds in the hard segments, while the good mobility of the soft segments is maintained. Additionally, the strong photothermal effect of Cu-pyridine coordination greatly promotes the healing speed of the elastomer.

Summary: In this work, a multiblock polyurethane (PU-Im) with imidazole dangling groups is demonstrated, which can coordinate with Ni2+ to form PU-Im-Ni complexes. By controlling the ligand content and metal-ligand stoichiometry ratio, PU-Im-Ni complexes with different mechanical behavior can be obtained. These complexes show excellent mechanical performance, thermal/aquatic self-healing ability, and unique damping properties, making them potential candidates for self-healing engineering plastic and cushion protection fields.

Summary: This paper reports the modification of HTPB polyurethane by incorporating 2-hydroxy-3,5-dinitropyridine (DNP) covalently into the matrix, leading to self-healing properties. The self-healing ability was observed by optical microscope, with a healing efficiency of up to 96% observed by UTM analysis. Additionally, the functionalized polyurethane demonstrated catalytic activity towards the thermal decomposition of Ammonium Perchlorate (AP), resulting in a lowering of the decomposition temperature by 73 degrees C. This two-in-one strategy of incorporating self-healing and catalytic activity in the polymer chain allows for the production of advanced binders for energetic formulations.

Summary: Sustainable self-healing polyurethanes have been developed using bile acid units and oligo(ethylene glycol)s as hard and soft segments, respectively. These polyurethanes exhibit similar mechanical performance to soft tissues and achieve a high self-healing efficiency of 90% in tensile strength. Multiple hydrogen bonds from bile acid hydroxyl groups and urethane bonds contribute to the self-healing ability, making them the first reported elastomers with quadruple hydrogen bonds from sustainable molecules. With their desirable biocompatibility in vitro and in vivo, these metal-free self-healing polyurethane elastomers are expected to find practical applications in soft tissue repair.

Summary: Mechanoluminescent (ML) materials can emit visible light through mechanical energy, making them advantageous for visual mechanical sensing and displays. Most organic ML materials lose their luminescence intensity with force stimulation, but a novel carbazole derivative (Cz-alkyl6) shows ML emission with self-assembly units and can be regenerated by recrystallizing the fracture crystal after a short thermal treatment. This allows for a quantitative correlation between force pressure and ML intensity, enabling the ML device to detect mechanical signals and potentially be used in engineering damage detection and anticounterfeiting.

Summary: This study analyzed the fracture evolution and rockburst phenomena of rockburst specimens under different stress gradient loadings using a large-scale true-triaxial gradient and hydraulic-pneumatic composite loading rockburst test device. The results indicate that the stress gradient has a significant influence on the fracture characteristics, with the decrease of failure stress and the increase of dynamic failure characteristics as the stress gradient increases. The increase of stress gradient contributes to higher fragmentation degree of debris, more uniform distribution, and better continuity.
