Reversible Diels–Alder Reaction To Control Wrinkle Patterns: From Dynamic Chemistry to Dynamic Patterns

Abstract

A facile and robust strategy to produce a reversible wrinkle pattern is presented by controlling a dynamic D-A reaction between furan and maleimide. The smart surface with highly reversible morphology and tunable adhesion, wettability, self-healing, and transparency is realized by the thermoreversible generation and erasure of the wrinkle pattern, which might find broad applications in functional intelligent materials with properties that can be tuned on-demand without altering the material's intrinsic properties.
