A novel organic–inorganic nanocomposite material of rare earth ions/ poly(styrene‐alt‐maleic anhydride) ionic salt/ reduced graphene oxide (Re3+/SMA‐Is/rGO) was prepared successfully. Poly(styrene‐alt‐maleic anhydride) ionic salt functionalized reduced graphene oxide (SMA‐Is/rGO) was processed with two methods of π–π conjugation and ionization; rare earth ions (Re3+ = La3+, Ce3+ Pr3+) was doped on the surface of rGO by physical mixing. SMA‐Is reduced surface energy and enlarged the interlayer spacing between rGO nanosheets, ensuring that Re3+/SMA‐Is/rGO could form a uniform dispersed phase in the organic coating. The anti‐corrosion performance of the nanocomposite coating was measured by electrochemical techniques in corrosive medium, revealing that introducing the nanocomposite to epoxy matrix exhibited a significant decline of the increase of corrosion potential and corrosion current density. In all samples, La3+/SMA‐Is/rGO had the highest anti‐corrosion performance, and the protection efficiency on mild steel was up to 98.97%.

A new generation of elastomer is expected to incorporate exceptional healing, reprocessing, damage-tolerant capacity and outstanding strength and toughness in view of a sustainable society. To search a suitable method to perfectly match the overall performance is yet a formidable challenge. Here, a thermaltriggered self-healing polyurethane composite elastomer was fabricated by crosslinking isocyanate terminated polyurethane with amidoxime-modified silica particles. The rigid fillers (silica particles) can effectively dissipate energy under an external force. The prepared particles and elastomer were detailly characterized by various instruments. The developed elastomer (POUs@2SiPs) had great tensile strength (39.47 MPa), decent elongation at break (1056.51%), excellent toughness (170.58 MJ m À3 ) and outstanding fracture energy (81.14 KJ m À2 ). Meanwhile, the well-designed healing capability enabled the material to regain its original mechanical performance and integrity after damage. In addition, the reprocessibility granted material reusability to extend the service lifespan. This work is supposed to provide a meaningful strategy for developing the elastomer, which can effectively balance those conflict properties of mechanical strength, damage-tolerant capacity and self-healing.
