The present disclosure provides a method for preparing a microcapsule and a microcapsule prepared thereby capable of selective release of oils and preventing volatilization of oils while maintaining long-term performance by improving storage stability of the oil contained in the capsule.

Method for preparing microcapsule

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.
