HYDRO-INSENSITIVE ELECTROLUMINESCENT DEVICES AND METHODS OF MANUFACTURE THEREOF

摘要

A composite is disclosed for use in electro-luminescent devices. The composite includes polymeric material having a first surface energy, and phosphorescent material dispersed within said polymeric material. The phosphorescent material has a second surface energy, said first and second surface energies are each between about 32 dynes/cm and 46 about dynes/cm. The polymeric material has a moisture vapor transmission rate of at least one gram/100 sq. inches for a 24 hour period at 100° F. for a one mil thick barrier.
