Zusammenfassung:	In the present specification, provided is a self-healing microcapsule with a core-shell structure comprising: a core including a self-healing polymer resin; and a first shell including a polymer of formaldehyde (F) and urea (U). When a capsule is destroyed by stimulation such as an external force or electric force (electric tree), the self-healing microcapsule can heal a damaged area by chemical bonding between an internal core material and a composition of an outer layer. 본 명세서에서는, 자가 치유 고분자 수지를 포함하는 코어; 및 유레아(U) 및 포름알데히드(F)의 중합체를 포함하는 제1쉘;을 포함하는 코어-쉘 구조를 갖는, 자가 복원 마이크로 캡슐이 제공된다. 이러한 자가 복원 마이크로 캡슐은 외부의 외력 또는 전기적 힘(전기트리) 등과 같은 자극을 받아 캡슐이 파괴되면 내부의 코어재와 외각층의 조성물이 화학적 결합으로 손상부위를 복원할 수 있다.
