Abstract
The present disclosure relates to a method for preparing a biodegradable and eco-friendly organic-inorganic hybrid microcapsule having few toxic substances with high versatility and economical efficiency by using a pickering emulsion method with a specific outer wall reinforcing material, a reactive material, and inorganic nanoparticles, and allowing polymerization of the outer wall reinforcing material and the reactive material to proceed at the interface. Specifically, the organic-inorganic hybrid microcapsule can stably support an active ingredient and then effectively express its activity by pressure, and exhibit a characteristic of gradually releasing the active ingredient at room temperature.
