“…Strategies for targeted introduction of pathways for inhibitor diffusion include the addition of particles leading to pathways of enhanced transport along the particle/matrix interface. [ 34 ] The existing knowledge accumulated so far for standard coatings based on leachable pigments will be valuable also for developing superior smart coatings, based on stimuli‐responsive release.…”

Organic coatings are one of the most popular and powerful strategies for protecting metals against corrosion. They can be applied to in different ways, such as by dipping, spraying, electrophoresis, casting, painting, or flow coating. They offer great flexibility of material designs and cost effectiveness. Moreover, since about 20 years self‐healing has evolved as a new research topic for protective organic coatings. Responsive materials play a crucial role in this new research field. However, for a really targeted development of high performance self‐healing coatings for corrosion protection, it is not sufficient just to focus on smart responsive materials and suitable active agents for self‐healing. A better understanding of how coatings can react on different stimuli induced by corrosion, how these stimuli can spread in the coating and how the released agents can reach the corroding defect is also of high importance. Such knowledge would allow to design coatings which are optimised for specific applications. Herein, the requirements and possibilities from the corrosion and synthesis perspectives for designing materials for preparing self‐healing coatings for corrosion protection are discussed.This article is protected by copyright.

Mimicking the characteristics and achieving specific functions of biological systems is stirring but challenging. Generally, pigments in the commercial coating can only achieve a similarity in chromaticity, while cannot obtain a similarity in the solar reflective spectrum whose difficulty resides in simulating spectral characteristics simultaneously. Unfortunately, traditional organic pigments show poor weather and heat resistance. Herein, with the little difference in the color difference (ΔEab*), the high spectral similarity, as well as adjustable green peak and similar red edge slope compared with the common plants (pagoda tree leaf, etc.) in 400–2500 nm, is also attained. It is achieved by the interlayer confined organic pigment in Mg/Al‐layered double hydroxide (Mg/Al‐LDH) layers. The corresponding biomimetic leaf displays high hyperspectral performance with a spectral angle cosine of 0.9922 and heat resistance at 120 °C. The longer weather resistance than that of mechanical mixing is also demonstrated. The intercalated chromophores of sodium copper chlorophyllin in the Mg/Al‐LDH and the interlayer confinement of Mg/Al‐LDH contribute to the excellent performance. This work provides a green pigment and a biomimetic leaf requiring the same chromaticity and spectrum as green plants, filling the long‐term use demand gap for heat and weather‐resistant biomimetic vegetation.
