▎ 摘　　要

NOVELTY - Composition comprises 0.01-15 pts. wt. graphene, 1-50 pts. wt. polyimide or its precursor, and 20-95 pts. wt. solvent. USE - The composition is useful for encapsulating transparent thin film of an organic electronic device (all claimed). ADVANTAGE - The composition has thermal dimensional stability, chemical resistance and excellent transparency, prevents penetration of oxygen and moisture, and improves durability of electronic devices. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for encapsulant including sealing film (5) prepared using the above composition. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the encapsulant. Transparent substrate (1) Organic sealing film (2) Inorganic sealing film (3) Pin holes (4) Sealing film (5)
