The present invention relates to: a polyether compound having a self-healing function, represented by chemical formula 1 and having a weight average molecular weight of 5,000-5,000,000, preferably 5,000-500,000; a preparation method therefor; and a polymer thin film formed therefrom. The polyether compound having a self-healing function, used in the present invention, is an economical material facilitating processing and capable of being readily coated on various substrates, and thus manufacturing a polymer thin film by using the polyether compound having a self-healing function is simple. In addition, the polymer thin film can repair micro-damage on the surface thereof by means of the self-healing characteristics of the polyether and, particularly, recovery ability is maximized and repeated effective recovery is possible by using a self-healing functional molecule. |
