Summary: In this study, the possibility of using a self-healing epoxy as an organic coating for metallic substrates was investigated. The recovery performance of the epoxy was evaluated through morphological observation, spectroscopic analysis, and mechanical and nanoindentation tests. The barrier properties and anti-corrosion performance were assessed through electrochemical impedance spectroscopy (EIS). The results showed that the coating could be repaired and restored its original properties after proper thermal treatment, indicating promising applications in the field of corrosion-resistant protective coatings and adhesives.

Summary: A more facile and efficient self-healing strategy for carbon fiber/thermoset resin interphase was developed based on the electrothermal effect of carbon fiber driving reversible transformation of covalent bonds. The introduction of DielsAlder cycloaddition adduct into the interphase region endowed the interface with thermoreversible covalent bonds, improving repair efficiency. Characterization of the modified carbon fiber was done through SEM, AFM, XPS, and TGA analysis, while adjusting the temperature range in CFRPs was achieved by controlling electric current applied to CFs. The self-healing behavior of the damaged interphase was verified through interfacial shear strength measurement, demonstrating the effectiveness of the electrothermal effect in promoting reversible transformation and improving interfacial adhesion.

Summary: The ability to form blends between the prepolymer and curing agent is crucial for efficient healing in self-healing materials. This study presents a new series of di- and tetrafuranic isocyanate-related ureas as promising curing agents for the development of polyurethanes-like self-healing materials. The self-healing properties of the materials were investigated by thermal analysis, and the resulting polyurethane showed thermally induced self-healing abilities.

Summary: The addition of an organomodified nanoclay to a carbon-based electrically conductive self-healing composite showed a synergistic improvement of the electrical conductivity and self-healing ability of the formed hybrid composites. The percolating network of conductive particles led to decent electrical conductivity, while the improvement of the self-healing properties was most pronounced just above the percolation threshold. These promising results suggest the use of the studied electrically conductive and self-healing hybrid composites for deformation and damage-sensing applications in flexible electronics and soft robotics.

Summary: In this study, two alicyclic dianhydrides with methyl substituents were synthesized and used to prepare high-performance polyimides for flexible electronic applications. The introduction of methyl substituents enhanced the properties of the polyimides, which formed flexible, transparent, and colorless films with superior optical transmittance and high thermal stability. These polyimides also showed excellent solubility in organic solvents, indicating potential applications as negative photosensitive polyimides.

Summary: The synthesis of cis-decalin structures using [4 + 2] cycloaddition with high stereoselectivity is challenging. In this study, we investigated the biosynthetic pathway of the fungal natural product fischerin (1) and identified a novel pericyclase, FinI, which catalyzes this reaction. The cocrystal structure of FinI, a predicted O-methyltransferase, with the product and SAM provides valuable insights into the natural formation of cis-decalin.

Summary: This article demonstrates that embedded piezoelectric sensors can withstand significantly higher loads than predicted, highlighting their potential for estimating structural loads in composites. Novel data acquisition methods allowed for wireless recording of ultrasonic guided wave measurements, showing reversible load dependence in the data recorded by piezoceramic transducers. Embedded sensors in glass fiber-reinforced composites showed no degradation after tensile strains, while sensors in carbon fiber-reinforced plastic degraded after high tensile stresses, suggesting potential for sensor development to characterize overload in components.

Summary: Linseed oil-in-water Pickering emulsions stabilized by sulfated CNCs and octylamine-modified CNCs exhibit different stability and self-healing properties. Octylamine-modified CNCs provide stronger resistance to creaming and smaller oil droplets compared to unmodified CNCs. Moreover, a CNC network at the oil-water interface protects the oil droplets from coalescence and enables self-healing of scratches on the coatings.
