Adhesive composition
Provided are an adhesive composition and an organic electronic device (OED) including the same, and particularly, an adhesive composition, which may form an encapsulation structure effectively blocking moisture or oxygen flowing into an OED from the outside, thereby ensuring the lifespan of the OED, realize a top-emission OED, and exhibit excellent adhesive durability and reliability, and an OED including the same.
CARBON FIBER SHEET FOR REINFORCEMENT
A reinforcing carbon fiber sheet (1) of the present invention includes: a carbon fiber filament (2) group arrayed in parallel in one direction; and a thermoplastic adhesive (4) present on at least part of the carbon fiber filament group in a direction across the carbon fiber filament group to unite the carbon fiber filament group. Preferably, the reinforcing sheet (1) includes a minimum amount of the carbon fibers required to produce a reinforcing effect. A sizing layer (3) of an epoxy-based resin is present on the surface of the carbon fiber filaments (2), and has a high affinity for the thermoplastic adhesive layer (4) present thereon, so that they strongly adhere to each other. Thus, the present invention provides a reinforcing carbon fiber sheet that is thin, has good handling properties and easily adheres to a substance to be reinforced.
