Patent ID: 8427855

Claim:
A nanocrystal composite comprising a matrix including a plurality of semiconductor nanocrystals, a barrier layer disposed on at least a portion of the surface of the matrix and including a polymer with low oxygen permeability, low moisture permeability, or both, and at least one functional layer disposed under at least a portion of the barrier layer, wherein the polymer with low oxygen permeability comprises a polymer having an oxygen permeability of not higher than about 10,000 mL/m 2 /day at a relative humidity of 0% or not higher than about 100,000 mL/m 2 /day at a relative humidity of 90%, and wherein the polymer with low moisture permeability comprises a polymer having a moisture permeability of not higher than about 10,000 g/m 2 /day at a relative humidity of 90%, and wherein the functional layer comprises an adhesive polymer selected from the group consisting of polyethylene, polypropylene, polystyrene, a copolymer thereof, and a mixture thereof.
