The edge self-sealing quantum dot film comprises a quantum dot layer, wherein the upper surface and the lower surface of the quantum dot layer are respectively provided with a water-oxygen isolating layer, and the edge self-sealing quantum dot film is characterized in that the quantum dot layer is composed of the following raw materials: 20-30 parts of modified polyacrylate, 10-20 parts of quantum dots, 0.5-1.5 parts of dispersant, 0.5-1.5 parts of flatting agent, 0.5-1.5 parts of photoinitiator and 20-30 parts of solvent; wherein the modified polyacrylate is subjected to crosslinking modification, and crosslinking groups are introduced into the polyacrylate chain segment. After the quantum dot film is cut off, polyacrylate branched chains in the quantum dot layer are further crosslinked to form an interpenetrating network structure with high crosslinking density under the irradiation of an ultraviolet lamp, so that the quantum dot layer is sealed, the quantum dots are isolated from water and oxygen, the service life of the quantum dot layer is ensured, the edge self-sealing process is not limited by the edge profile of the film, and the quantum dot film is suitable for the inner edges of films such as complex film edge structures or positioning holes. |
