| Abstract | Intelligence polymeric coatings with excellent self-healing ability and mechanical properties, as well as fine shielding and durability, are of enormous significance to metal corrosion protection technology. Herein, a novel biomimetic nanocomposite coating was obtained by integrating self-healing bio-based polymer and modified graphene oxide hybrids into the artificial nacre material system in this work. Based on the formation of a typical nacre-like structure, the material shows excellent strain resistance (617%) and ultimate tensile strength (5.1 MPa), realizing a special combination of practical repair performance and mechanical strength of the wise coating. Benefiting from the high internal resin network density quadruple dynamically reversible supramolecular hydrogen bonds, the coating material exhibited an exceptional and efficient self-healing ability at room temperature (10 min). In addition, the distinguished long-term corrosion media barrier properties of the biomimetic coating are endowed by graphene oxide (GO) platelets with high barrier properties. Importantly, the selection of bio-based epoxy resins improves the sustainable economic application of engineered coatings in contrast to the application of traditional epoxy resin coatings. Therefore, this kind of bio-based biomimetic coating displays broad application potential as an intelligent self-healing protective material in electronic devices, engineering equipment, and other fields. |
