Raspberry‐shaped redox‐responsive capsules for storing corrosion inhibitors are introduced, targeted to solve the drawbacks of conducting‐polymer‐based coating systems for corrosion protection. These capsules synthesized via the miniemulsion technique have a remarkable release property upon reduction (onset of corrosion) and cease release upon reoxidation (passivation of the defect). The self‐healing capability is demonstrated by application of these capsules as part of a composite coating on zinc.
