This invention relates to polymer-based partially-open, hollow reservoirs in the nano-size to micro-size range that encapsulate an additive, which can be released from the reservoirs using specific event stimuli such as reduction-oxidation and voltage change, or at will, using the same stimuli. This invention also relates to method preparing such reservoirs, and for releasing the additive. This invention further relates to matrix that comprises such reservoirs and the method of preparing such matrix. This invention also relates to applications, for example in corrosion inhibition, lubrication, and adhesion, that benefit from using such a controlled release of an additive.
