Interfacial Thermoreversible Chemistry on Functional Coatings: A Focus on the Diels–Alder Reaction [* Cross-Reference *]

In most cases, the material itself is formulated to react to the corresponding stimulus. However, many phenomena occur at the surface of the material.

In this context, the design and the investigation of the reactivity of stimuli-responsive surfaces are particularly interesting. More precisely, this review focuses on functional coatings that react via Diels–Alder (DA) chemistry, a thermoreversible reaction between a diene and a dienophile. According to the nature of the substrate, these coatings are mainly based on self-assembled monolayers or silane assemblies, on polydopamine derivatives, or on polymer thin films deposited by vapor-phase processes including plasma polymerization.
