Abstract

The incompatibility of nanomaterials with resin and the irreversibility of coatings after damage severely limit the anti-corrosion and anti-wear properties of epoxy coatings. Hence, in this work, a f-BNNs-ZB@AFD-EP composite coating with active/passive self-healing properties was prepared to provide excellent corrosion and wear protection. Boron nitride nanosheets with a high aspect ratio were prepared by mechanical exfoliation, and their compatibility with resin was enhanced by polyethyleneimine. The release of benzotriazole from the zeolitic imidazolate framework on the nanosheets and the reconnection of disulfide bond provided excellent active/passive self-healing properties. Moreover, the coating resistance of f-BNNs-ZB@AFD-EP (2.49 × 10⁷ Ω⋅cm²) was increased by three orders of magnitude pure epoxy coating (7.95 × 10⁵ Ω⋅cm²). Meanwhile, the friction coefficient (0.64) and wear rate (5.00 × 10⁻⁵ mm³/N·m) of f-BNNs-ZB@AFD-EP were lower than that of pure composite coating (0.78, 3.50 × 10⁻⁴ mm³/N·m). The f-BNNs-ZB@AFD-EP with outstanding properties has great application prospects in the field of material protection.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
