Description
Summary:A glue, based on dynamic covalent chemistry, with a strong adhesion (2.38 kg cm−2), water resistance and carbohydrate responsive reversibility is presented. Using surface initiated atom transfer radical polymerization (SI‐ATRP), glass and silicon surfaces were coated with copolymers functionalized with phenylboronic acids and catechols. In combination with microcontact printing (μCP) these polymer brushes give access to a carbohydrate responsive “supramolecular Velcro”. Glue and release: A supramolecular glue is prepared through the combination of atom‐transfer radical polymerization and the dynamic covalent chemistry of phenyl boronic acids and catechols. The glue shows strong adhesion (2.38 kg cm−2), is water resistant, can be reused multiple times, and releases in the presence of a carbohydrate.
