Film and electronic device comprising same

Abstract

Provided are a film and an electric device comprising the same. The film comprises at least one modified polyolefin resin layer. A resin forming the modified polyolefin resin layer comprises 1-100% of modified polyolefin resin. A main chain in the modified polyolefin resin is an ethylene-α-olefin copolymer. A grafted branched chain in the modified polyolefin resin is selected from a compound formed by a vinyl monomer comprising one or more of anhydride group, hydroxyl, ester group, carbonyl, acylamino, pyridyl, epoxy, pyrrolidonyl and glycidyl. A molecular weight of the grafted branched chain is 150-8000 g/mol. The film prepared from the modified POE layer with the main chain and the grafted branched chain has excellent anti-PID performance. The layers have a better adhesive property without a laminated interface therebetween. The co-extruded film further has an excellent water vapor barrier property, a relatively high insulating property and a relatively high light transmittance.
