Self-healing multi-component polyimide composition and film, and method for manufacturing the same

Abstract

The present disclosure provides a polyimide resin composition capable of repeated self-restoration, comprising a combination of multi-component polyimides and exhibiting excellent transparency and mechanical property, and a film comprising the polyimide resin composition. The film according to the present disclosure shows a self-restoring property that can self-heal a damage such as crack or shape deformation occurring at a room temperature, and can extend a life of the film and reuse it in virtue of repeatability of the self-restoring property. In the present disclosure, the polyimide resin composition can be used as an adhesive or a coating agent for electrical and electronic materials, and, for example, can be usefully used as a cover window for protecting the surface of a mobile device or a display device.
