Abstract
Controlled release particles may include stimuli-responsive coatings on porous particles to allow for controlled release of a material in the pores of the porous particles. For example, a composition may comprise: a porous particle; a material in pores of the porous particle; and a coating bonded to a surface of the porous particle, wherein the coating comprises a multi-urethane compound capable of reversibly converting between a condensed state and an expanded state upon exposure to a stimuli.
