Title:

ADHESIVE FILM AND ELECTRONIC DEVICE COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2021/253612

Kind Code:

A1

Abstract:

Provided are an adhesive film and an electronic device comprising same. The adhesive film comprises at least one modified polyolefin resin layer, wherein the resins for forming the modified polyolefin resin layer comprise 1%-100% of a modified polyolefin resin, wherein the main chain of the modified polyolefin resin is an ethylene-α-olefin copolymer, a grafted branch chain is selected from a compound formed by vinyl monomers containing one or more of an anhydride group, a hydroxyl group, an ester group, a carbonyl group, an amido group, a pyridyl group, an epoxy group, a pyrrolidone group and a glycidyl group, and the molecular weight of the grafted branch chain is 150-8000 g/mol. An adhesive film prepared by selecting and using a modified POE layer with the main chain and the grafted branch chain described above has excellent PID resistance; when the modified POE layer and an EVA layer form a co-extrusion adhesive film, the layers have a good bonding performance, there is no lamination interface, and the co-extrusion adhesive film further has an excellent water vapor barrier performance, relatively high insulation performance and relatively high light transmittance.
