Molecularly Smooth and Conformal Nanocoating by Amine-Mediated Redox Modulation of Catechol

Conformal nanocoatings to nanostructured materials are key to the utilization of unique nanomaterial properties. Although catechol-based nanocoatings on flat substrates have been extensively reported, research on conformal coatings to nanomaterials with high curvature has rarely been conducted because cohesion is caused by the catechol oxidation. In the literature, amine-mediated redox control of a catechol system by separating catechol and amine is employed and an optimized nanocoating can be achieved by suppressed cohesion and enhanced adhesion. The amine-assisted catechol nanocoating exhibits roughness of
