英文摘要Localized corrosion is caused by less protection of the metal substrate, which causes catastrophic damage for load-bearing material. It is significant to rescue corroded areas in a smart and controllable manner. Herein, a newfangled strategy for directional repairing rGO-Fe3O4/Oil coating drove by magnetic force to mitigate local corrosion was proposed. The new directional repairing system was consisted of low-viscosity oil and magnetically responded rGO-Fe3O4 filler via hydrothermal synthesis. Easy-flowing oil acted as the driving of the selfhealing coatings because they can readily reconnect to heal minor flaw. Due to the synergistic effect of the magnetic responsiveness and the impermeability of rGO-Fe3O4, the flowable rGO-Fe3O4/Oil film can move to the corroded area under the action of magnetic field and effectively mitigated the corrosion examined by the scanning vibrating electrode technique (SVET). Moreover, the rGO-Fe3O4/Oil film was capable of repeating selfhealing ability in air, pH = 1 (acid), pH = 7 (salt), and pH = 14 (alkali) solutions at the same area. The excellent anti-corrosion performance of rGO-Fe3O4/Oil coating was attributed to rGO-Fe3O4 tremendously improved its physical barrier effect and prolonged the penetration path of the corrosive mediums. Such a strategy could offer a potential approach for the preparation of anticorrosion materials that could accurately and intelligently repaired the localized corrosion on metal substrate.
