Abstract:
An electrically conductive multilayer composite comprises first and second polymeric films, each being flexible and having upper and lower surfaces, with the second films being thermoformable at temperatures at and above its glass transition temperature. A flexible electrically conductive layer is applied to the upper surface of the first films, and an adhesive interlayer adheres the lower surface of the first film to the upper surface of the second film. The adhesive inter layer has elastic properties sufficient to accommodate relative movement between the thus adhered films occasioned by flexure of the composite.
Abstract:
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 a at least one gram/100 sq. inches for a 24 hour period at 100 °F for a one mil thick barrier.
Abstract:
An alternating current responsive composite is disclosed. The composite includes a polymeric material and a polar material that is substantially dispersed within the polymeric material. The polar material is responsive to the presence of an alternating current.
Abstract:
A water vapor permeable composite is disclosed for use in electroluminescent devices. The composite includes polymeric material having a first surface energy, a phosphorescent material dispersed within at least a portion of said polymeric material; and an electrically conductive material on at least one side of said polymeric material. The conductive material has a second surface energy, said the 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.
