Title:
ADHESIVE COMPOSITION AND PREPARATION METHOD THEREFOR, AND OPTICAL ADHESIVE FILM AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/116494
Kind Code:
A1
Abstract:
The present application provides an adhesive composition. The adhesive composition comprises an adhesive matrix and a modified polymer, wherein the backbone of the modified polymer comprises a boron-oxygen coordinate bond and/or a bridging boron-oxygen coordinate bond, and the end group and/or side chain of the modified polymer comprises at least one of a hydroxyl group, an acrylate group, and a vinyl group. The present application further provides a preparation method for the resin composition, an optical adhesive film, a folding screen using the optical adhesive film, and an electronic device using the optical adhesive film or the folding screen. According to the present application, a boron-oxygen coordinate bond and/or the bridging boron-oxygen coordinate bond is introduced to the molecular backbone of the modified polymer, so that the adhesive composition has excellent energy absorption and impact resistance performance while ensuring the adhesion strength, thereby improving the impact resistance performance of the folding screen, and reducing failures of a panel, such as black spots or broken bright spots, caused by external impact.
