Acid-cleavable polymers for simultaneous fast and slow release of functional molecules

Hydrophobic copolymers are designed to respond to acid stimuli for both simultaneous rapid and sustained release of multiple cargos. Three different types of corrosion inhibitors were conjugated to a single copolymer via three types of acid-sensitive linkages. The release rate of each corrosion inhibitor was controlled by the lability of the linkages, allowing a co-release of corrosion inhibitors.
