Summary: The surface of PBO fibers was modified by a hybrid coating consisting of polydopamine (PDA) and 3-aminopropyltrimethoxysilane (KH551) hydrolysis products using a mussel-inspired co-deposition strategy, leading to increased surface roughness and wettability. The resulting hierarchical reinforcement showed a significant enhancement in interfacial shear strength (IFSS) without compromising tensile strength (TS), as well as improved atomic oxygen (AO) erosion and hydrothermal aging resistances. The one-step mussel-inspired surface modification strategy offers a simple and cost-effective approach for fabricating multifunctional hierarchical reinforcements.

Summary: A mussel inspired co-deposition of ferric ion-polydopamine (PDA) on carbon fiber is developed to enhance the interfacial adhesion of epoxy composites. The effects of ferric ion contents on fiber surface characteristics and interfacial adhesion are investigated. The formation of bis-and tris-Fe3+-catechol complexes is affected by the addition amount of FeCl3, while the level of Fe3+ ions significantly impacts DA oxidation. The surface modification with ferric ion-PDA complex can increase the interfacial shear strength by enhancing the interfacial crosslinking density.

Summary: In this study, porous graphene oxide was used as a nanoscale reinforcement to improve the interfacial adhesion in composites, resulting in significantly higher interfacial shear strength compared to untreated fiber and GO/fiber reinforcement. The enhancement was attributed to rich interfacial interactions and improved surface energy through the synergistic effects of polyethylenimine, as well as the formation of a rigid-soft transition zone for stress dissipation. The advantages of porous graphene oxide suggest potential for further advancements in composite materials by carefully designing its properties.

Summary: A core-shell ZrO2@GO hybrid was prepared and incorporated onto carbon fiber via dip-coating to enhance the interfacial adhesion of epoxy composites. The ZrO2@GO functionalized fiber composite showed the highest interfacial shear strength, with significant improvements over untreated fiber, only epoxy sizing coated fiber, and silane coupling agent-encapsulated ZrO2 decorated fiber composites. The enhanced adhesion was attributed to improved resin wettability, multiple interactions between GO and epoxy resin, and the formation of a mobile network absorbing energy.

Summary: By using a biomimetic surface modification strategy, the interfacial adhesion property of UHMWPE fibers reinforced rubber composites was significantly improved. The deposition of nano-ZnO was achieved through the synergistic effect of dopamine and zinc oxide nanoparticles. The results showed that the adhesion strength between the modified fibers and the rubber matrix was greatly enhanced, which could be attributed to the combined action of interfacial physicochemical interactions and mechanical interlocking.

Summary: A modified three-point bending technique was proposed to measure the interfacial toughness of thick plasma sprayed ceramic coatings. The test involved creating a pre-crack and measuring crack propagation along the interface using a pop-in load. Finite element analysis was used to calculate the interfacial toughness. The results were compared with the tensile adhesion test, and a correlation was proposed between the two methods.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
