Abstract
A method of preparing a self-healing composition is disclosed, the method including following steps. An isocyanate solution, a dihydric alcohol solution, and a metal salt solution are provided. The dihydric alcohol has heterocyclic structures. The isocyanate solution and the dihydric alcohol solution are mixed, causing the isocyanate and the dihydric alcohol polymerize to form a polymer precursor. The polymer precursor includes a hard segment and a soft segment. The hard segment includes urethane groups, the soft segment includes heterocyclic structures. The polymer precursor and the metal salt solution are mixed, causing the heterocyclic structures and metal ions to undergo a chelation reaction to form a coordination complex, thereby forming the self-healing composition. A self-healing composition prepared by the method, and self-healing film using the self-healing composition are also disclosed.
