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.

Abstract: A capsule for a lithium-sulfur secondary battery, the capsule comprising a core containing a material capable of forming and restoring a solid electrolyte interface layer and a hydrogel; and a shell formed of a polymer and surrounding the core, is provided. The capsule maintains the solid electrolyte interface layer on a negative electrode for a long time by maintaining the material capable of forming and restoring the solid electrolyte interface layer at a constant level during operation of the lithium-sulfur secondary battery.

Abstract: A capsule for a lithium-sulfur secondary battery, wherein the capsule includes a core containing a material required for formation and restoration of a solid electrolyte interface layer (SEI layer) and a shell including a polymer surrounding the core. The shell maintains the material required for formation and restoration of the solid electrolyte interface layer (SEI layer) at a constant level during operation of the battery, thereby exhibiting the effect of maintaining the solid electrolyte interface layer (SEI layer) on the negative electrode for a long time.

Abstract: The present invention relates to a controlled-release fertilizer, including: a photodegradable capsule including a binder resin containing a polyolefin and an ethylene vinyl acetate copolymer, and a photocatalytic composite in which a (co)polymer including at least one repeating unit selected from the group consisting of an ethylene repeating unit and a vinyl acetate repeating unit is bonded to the surface or inside of agglomerates of inorganic fine particles; and a fertilizer contained in a space surrounded by the photodegradable capsule.

Abstract: The present disclosure relates to a controlled-release fertilizer and, more particularly, to a controlled-release fertilizer including: a photodegradable capsule including a binder resin containing a polyolefin and an ethylene vinyl acetate copolymer; and a photocatalytic composite in which a (meth)acrylate compound containing an alkylene glycol repeating unit having 1 to 10 carbon atoms is bonded to the surface or inside of aggregates of inorganic fine particles, and a fertilizer contained in a space surrounded by the photodegradable capsule.

Abstract: The present disclosure relates to a controlled-release fertilizer and, more particularly, to a controlled-release fertilizer comprising a photodegradable capsule including a binder resin containing a polyolefin and an ethylene vinyl acetate copolymer; and a photocatalytic composite in which a surfactant having an HLB value of 1 to 6 is bonded to the surface or inside of aggregates of inorganic fine particles, and a fertilizer contained in a space surrounded by the photodegradable capsule.

Abstract: 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.
