| 英文摘要 | Fiber-reinforced composite coatings (FRCCs) are promising for marine protection, but insufficient adhesion at both the fiber/resin and resin/metal interfaces continues to limit their long-term durability. In this work, FRCCs were prepared by electrospinning poly(vinylidene fluoride) (PVDF) nanofibers modified with myristic-acid functionalized kaolin onto epoxy (EP), polyurethane (PU), and fluorocarbon (FC) pre-coated steel. Multiscale characterization (SEM, EIS, mechanical testing, salt spray testing, electromagnetic flux monitoring, and molecular dynamics simulations) revealed that variations in both fiber/resin and resin/metal interfacial adhesion mechanisms accounted for the distinct performance of the three systems. EP-based coatings displayed strong adhesion at the metal interface but limited long-term durability, PU-based coatings showed balanced impact resistance and anticorrosion performance, whereas FC-based coatings offered superior long-term anticorrosion durability but relatively weaker mechanical robustness. An electromagnetic flux method developed in this study captured permeability-driven changes associated with Fe to FeO transformation and tracked interfacial delamination at the coating/metal interface in real time, with signal evolution consistent with EIS data trends and a detection time below 10 s. Molecular dynamics simulations (MDS) further demonstrated that hydrogen bonding dominates fiber/resin adhesion, with PVDF/PU interfaces exhibiting the strongest bonding, followed by PVDF/ EP and PVDF/FC, consistent with experimental observations. These findings highlight the dual interfacial mechanism that govern coating durability and provide a framework for the rational design of next-generation FRCCs for marine applications. |
