Acid-induced Control of Surface Properties Using a Catecholic Silane Coupling Reagent

Herein, we present a method for controlling the surface properties of a substrate through exposure of the catechol group by acid stimulation. The results showed that the wettability and adhesion properties of the surface of the substrate can be controlled by acid treatment or UV irradiation in the presence of a photoacid generator. These findings will provide new insights into the development of materials with controlled surface properties.
