Abstract

We report a simple route to engineer ultrathin polymer brush surfaces with wrinkled and creased morphologies using postpolymerization modification (PPM), where the length scale of the buckled features can be tuned using PPM reaction time and sequence. We show that partial crosslinking of the outer layer of the polymer brush under poor solvent conditions is crucial to obtain wrinkled morphologies upon swelling. Sequential postmodification reactions enable wrinkle‐to‐crease and wrinkle‐to‐wrinkle morphological transitions while endowing the brush with additional chemical functionality.
