“…It is well known that the adhesion can be further enhanced by adding a hydrophilic resin as an adhesive in the construction of SHPL composite coatings and SiO 2 NPs. 34 As shown in Fig. 2(b), compared with the uncoated glass, the WCA of the coated surface was less than 5°, reaching a super hydrophilic state.…”

The application of self-healing polymers in corrosion protection is often limited by their slow and nonautonomous healing ability and poor long-term durability. In this paper, we propose a double-layered transfer self-healing coating constructed by soft and rigid polymer layers. The soft polymer has a fast self-healing rate of 10 min to repair, which was found to accelerate the self-healing of the upper rigid layer. The rigid polymer provided relatively high barrier ability while preserving certain self-healing ability owing to the shear-thinning effect. In this way, the double-layered coating combined rapid self-healing (∼1 h) and high impedance modulus |Z| f-0.01 Hz of 2.58 × 10 10 Ω•cm 2 . Furthermore, the introduction of pyridine groups in B-PEA and polyacrylate-graf ted-polydimethylsiloxane (PEA-g-PDMS) induced the Fe ionresponsive ability and shortened the self-healing time to 40 min (100 ppm Fe). Finally, barrier and anode sacrificed layers were introduced to produce multilayered architecture with active/ passive anticorrosion performance. In the presence of scratches, the |Z| f-0.01 Hz can be preserved at 1.03 × 10 10 Ω•cm 2 after 200 days. The created anticorrosive coating technology combines long-term durability with room temperature autonomous rapid self-healing capability, providing a broad prospect for anticorrosive applications.

“…The structure of polymer coatings, which can be controlled by altering the content of the polymer, has a significant impact on their capacity for self-healing and corrosion protection. [18] In this study, polymer coatings of PEI-C with PAA 45w -PAA 2000 were prepared on the stainless steel surface by layer-by-layer assembly method. In order to study the surface morphology and anticorrosion performance of the coating with different PAA2000 content, samples with a PAA 2000 content of 0.5 mg/mL, 1.0 mg/mL, 1.5 mg/mL and 2.0 mg/mL were prepared.…”

Self‐healing coatings offer tremendous application prospects in the field of preventing metal corrosion because of their superior functionality. The coordination of barrier performance and self‐healing ability, however, continues to be difficult. Herein, a polymer coating based on polyethyleneimine (PEI) and polyacrylic acid (PAA) with self‐repairing and barrier ability was designed. Introducing the catechol group into the anti‐corrosion coating increases the adhesion and self‐healing efficiency of the coating, providing a guarantee for the long‐term stable bonding between the anti‐corrosion coating and the metal substrate. Small molecular weight PAA polymers are added to polymer coatings to increase their self‐healing capabilities and corrosion resistance. Because layer‐by‐layer assembly creates reversible hydrogen bonds and electrostatic bonds that help the coating repair itself when it is damaged, and because the traction of small molecular weight polyacrylic acid speeds up this process. When polyacrylic acid (PAA) with a molecular weight of 2000 was present in the coating at a concentration of 1.5 mg/mL. The PEI‐C/PAA45W‐PAA2000 coating has the fastest self‐healing, and the corrosion resistance efficiency (Pe) was as high as 90.1%. The polarization resistance (Rp) was maintained at 7.67×104 Ω∙cm2 after immersion for more than 240 h. It was better than other samples in this work.
