Ionic cycloolefin polymer, photo-self-repairing material based on ionic cycloolefin polymer, and preparation method and application of photo-self-repairing material

The invention discloses an ionic cycloolefin polymer, a photo-self-repairing material based on the ionic cycloolefin polymer, and a preparation method and application of the photo-self-repairing material, and belongs to the technical field of self-repairing materials. Reversible ions exist in the structure of the prepared ionic cycloolefin polymer, and the polymer shows excellent photothermal conversion capacity under infrared light, so that the polymer has efficient repairing performance under light stimulation; and meanwhile, a Grubbs 3 ruthenium catalyst adopted in the preparation process of the self-repairing material is used for catalyzing ring-opening metathesis polymerization, and after the polymerization reaction is completed and a terminating agent is added, a Grubbs 3 derivative obtained by reacting the Grubbs 3 ruthenium catalyst with the terminating agent also has an excellent photothermal effect, so that a photothermal conversion agent does not need to be additionally added, and the application o
