Summary: Fluorinated boron nitride nanosheets (F-BNNSs) with different fluorine contents were successfully prepared via solvothermal method, showing superior tribological performance. The F-BNNSs with the highest fluorine content exhibited the best friction coefficient and wear rate, attributed to their special composition, physicochemical properties, nanostructure, and interface behaviors.

Summary: The study investigates the impact of UHMWPE particle size on its performance, as well as the effect of processing. While minor differences in properties among different grades of UHMWPE were observed, they are not sufficient to definitively determine the influence of particle size and processing on the material's properties and performance.

Summary: In this paper, a highly moisture-resistant fluorinated polyimide composited with an amorphous fluoropolymer film was prepared. The charge injection performance, triboelectric performance, and moisture resistance of the composite film were investigated. In addition, a self-powered, highly sensitive, and moisture-resistant porous-structure acoustic sensor based on contact electrification was developed, and the detection characteristics of the acoustic sensor were obtained.

Summary: The study focuses on the tribological and mechanical properties of the mollusk shell (MS)-ultrahigh molecular weight polyethylene (UHMWPE) biocomposite against stainless steel. Results show that the addition of MS particles enhances the mechanical properties of UHMWPE, while the biocomposite exhibits high tribological performance compared to pure UHMWPE in terms of specific wear rate and coefficient of friction. The correlation between mechanical and tribological properties is examined, with the coefficient of friction showing reasonable correlation with hardness, fracture strain, fracture strength, and Young's modulus of the MS-UHMWPE biocomposite.

Summary: In this study, a fast self-healing and antifouling composite material called PFPMS was prepared. It exhibited excellent mechanical and antifouling properties, and achieved fast self-healing through the cross-linking reaction of ruptured microcapsules. The micro-nano-dual-scale surface formed by the microcapsules and nano-SiO2 contributed to the superior antifouling performance of PFPMS.

Summary: A novel hierarchical multifunctional flexible composite film is developed, which provides temperature regulation, electromagnetic interference shielding, and thermal management. The film is created by synthesizing phase change microcapsule (PCMC) latex through in-situ polymerization, mixed with waterborne polyurethane (WPU) latex, and dried using a binary colloidal approach. To enhance EMI performance and mechanical strength, a thin layer of antioxidant MXene@poly tannin acid (PTA) is sprayed onto the surface of the film. The resulting film exhibits exceptional thermal management performance and outstanding EMI performance, making it an ideal choice for future multifunctional products.

Summary: This study aimed to improve the strength and toughness of ultra-high molecular weight polyethylene (UHMWPE) fibers reinforced rigid polyurethane (RPU) composites. The satisfactory mechanical properties were mainly due to the copper-polydopamine composite coating, which provided more paths for crack propagation and chemical bonding, leading to significant increases in tensile, interlaminar shear, and impact strength.

Summary: The synergistic effect between nanomaterials with different dimensions can enhance wear and corrosion resistance of surface protective coatings. This study found that the GO-pva-SiC coating exhibits good lubricating performance under low load, while the RGO-pva-SiC coating has a longer wear life under high load. Furthermore, the addition of SiC nanowires can enhance the corrosion resistance of graphene-based coatings.
